TPS & partners take Automotive Power Electronics to the next level! £1.3M received by UK Gallium Nitride consortium for GaNTT project

TPS enters Vertical GaNTT consortium to advance Automotive Power Electronics

Hybrid and full Electric vehicles represent one key area where stakeholders from the automotive industry are increasingly concentrating their efforts to produce more efficient and cost-effective components, such as DC-DC converters. To support multiple stakeholders and advance the UK’s automotive sector, TPS has taken a collaborative role in the vertical GaNTT project led by the Compound Semiconductor Centre (CSC).

This visionary project has received £1.3m funding from the OLEV (the Office for Low Emission Vehicles) through “The road to zero emission vehicles” competition. We will be working alongside CSC and other partners from the power electronics supply chain such as Compound Semiconductor Applications (CSA) Catapult, Newport Wafer Fab and SPTS Technologies. The consortium will also receive academic support in the power systems arena from the University of Swansea and Coventry University.

Wide bandgap (WBG) semiconductors such as Gallium Nitride (GaN) are becoming one of the prevailing technologies in delivering more cost-effective, compact, lightweight and efficient power electronics systems for automotive applications such as Electric Vehicles. These facilitate outstanding system performance levels and can lead to lower lifetime costs compared to standard silicon.

Through GaNTT (Realisation of a mass manufacturable Vertical GaN Trench FET architecture), we aim to drive the development of a new process platform to advance Automotive Power Electronics where GaN is a core element. This voltage-scalable vertical GaN process platform (200V – 600V) will be suitable for, amongst others, Electric Vehicle applications and the resulting device will be evaluated in application as part of the project.

TPS will play an important role within the consortium as we will provide a Tier 1 automotive testing environment where we will assess prototype GaN devices against standard silicon by integrating them into a bidirectional DC-DC converter for EV.

Our vision is to deliver performance improvements that are in line with the Power Electronics Roadmap published by the Advanced Propulsion Centre (APC). The roadmap sets challenging cost and efficiency targets for future power devices that couldn’t be met with conventional silicon-based technology. The 2035 targets for inverters and DC-DC converters are ambitious and will only be possible to reach using wide band gap (WBG) materials such as GaN.

Vertical GaN architectures are ideal for low to medium voltage and power applications such as On-board Charging (OBC) and DC-DC applications where higher switching speed is favoured. Our new ground-breaking GaNTT project outlines a clear route to meeting these targets through a UK-based supply chain.

This cross-cutting technology will not only be beneficial for automotive applications, but also suitable for the aerospace, defence and space sectors. The outcomes of GaNTT project will deliver the ambitious COx and NOx reduction targets set by the UK government and therefore will have a positive impact on important environmental challenges to the benefit of all UK citizens.

Dr. Nigel Jakeman, TPS Engineering & Business Development Director, commented:
“Vertical GaNTT can deliver a new generation of device that can see Gallium Nitride finally being adopted in higher power applications. We’re delighted to be part of the program and to be working with our partners, in particular to be assisting with delivery of the exciting semiconductor devices of the future.“

Electrifying the UK – TPS enters pioneering partnership with industry leaders to develop first ever UK-centric supply chain for next-gen Silicon Carbide Power Electronics

TPS enters ESCAPE project to decarbonise transport through first UK supply chain of Silicon Carbide Power Electronics

TPS is at the forefront of decarbonising the transport landscape while taking on an important role in project ESCAPE, which aims to accelerate the UK’s low carbon capability within the automotive sector. We have teamed up with key players from the automotive and other UK-based manufacturing industries to facilitate the creation of an End-to-end Supply Chain for Automotive Power Electronics (ESCAPE).

Next generation Silicon Carbide (SiC) power semiconductors are a strategic technology that will play a fundamental role in decarbonising our transportation infrastructure. This project is critical to developing the SiC supply chain within the UK and has received £9.8m funding from the Advanced Propulsion Centre (APC) to create ground-breaking technology to support the drive for electrification in the UK and worldwide.

As part of this progressive initiative, TPS will develop a high-frequency rapid Electric Vehicle (EV) charger that directly connects to the Medium Voltage electricity distribution network. Such an approach diminishes the impact of EV rapid charging on local domestic substations and reduces the cost of necessary network reinforcement that will be required to support the drive towards vehicle electrification. Some of our key partners in this project are: McLaren Applied Technologies – project lead, AESIN (Operated by TechWorks), Compound Semiconductor Applications Catapult, Compound Semiconductor Centre (CSC), Clas-Sic Wafer Fab, Exawatt, Lyra Electronics, MaxPower Semiconductor, Tribus-D and The University of Warwick.

Wide bandgap SiC semiconductor technology is rapidly gaining market share, where standard silicon devices have historically dominated, and are becoming a core component in the development of power electronics (PE). This technology facilitates power conversion at remarkable levels of efficiency whilst enabling compact and lightweight electronic converter designs, hence lending themselves ideal to the automotive sector. Developing the Silicon Carbide supply chain from a UK base is essential and is to become increasingly relevant for many transportation sectors including automotive, railway, marine and aviation, and also non-transport applications such as electrical grid interfaces and renewable energy systems.

TPS’s rapid charger using SiC technology is an industry-enabling solution that underpins the electrification revolution, while delivering a suite of benefits to all parties involved:
– CO2/NO2 emissions reduction through the acceleration of EV uptake and helping the UK achieve its challenging Green House Gas emissions targets;
– Enabling rapid charge of longer-range Electric Vehicles, addressing range anxiety which has long formed a commercial barrier to market adoption;
– Operating from higher supply voltages to address concerns about infrastructure and reinforcement costs required to address existing electricity distribution network constraints.

Bearing this in mind, it is no wonder that the UK demand for SiC is on a rapidly rising trajectory, thus leading to a growing requirement for a UK-based supply chain. Domestic expertise in SiC manufacturing and integration into PE systems will allow more and more local manufacturers to include this technology into their processes, hence reducing dependency on international supply chain. Through this project, by securing access to the domestic supply chain, local companies will be able to take their SiC-based products to mature Technology and Manufacturing Readiness Levels. As a leading manufacturer of SiC-based power electronic solutions, TPS was eager to participate in ESCAPE to help facilitate the production of these strategic high value components and their resulting systems within the UK. SiC is one of the key elements that we have been utilising in our latest projects to improve efficiency, reduce weight and size and improve reliability.

As the vast majority of vehicles are still running on fossil fuels, their exhaust gases are responsible for a large proportion of the carbon dioxide produced in the UK. Making these vehicles electrically driven and providing the necessary EV charging infrastructure will ultimately lead to the elimination of emissions associated with transportation and mobility, as well as reducing the UK’s dependency on imported fossil fuels. ESCAPE aims to support the government’s targets of reducing carbon emissions by advancing the transition to zero emissions transport, while bringing together industrial leaders and pioneers from across the supply chain to work as team to deliver this vision.

Dr. Nigel Jakeman, TPS Engineering & Business Development Director, commented:
“We’re excited to be part of this strategic incentive which recognises, not just the importance of SiC technology to developing the automotive and charging infrastructure industry of the future, but also the importance that UK suppliers will have in making it happen. We look forward to working with our partners who span the full supply chain from wafer suppliers through to automotive OEMs to deliver something exceptional and with national significance over the next 3 and a half years”

TPS gives speech at Better Networks Forum on our next-gen power converters for Active Response

Wondering what TPS is up to? We are working on a new, much more efficient generation of power converters for both LV and MV networks, as part of Active Response:

Earlier this year TPS’s Engineering & Business Development Director, Dr. Nigel Jakeman, participated as one of the main speakers at the Better Networks Forum, event organised by our partners, UK Power Networks. Here he joined Alex Jakeman – Innovation Project Lead at UK Power Networks – in describing the intricacies of Active Response and our role in this ground-breaking project.

Dr. Nigel Jakeman speaking during Better Networks Forum - event hosted by UK Power Networks

Better Networks Forum took place on 23 January 2019 at the IET, Savoy Place in London and it focused on describing UK Power Networks’ innovative projects that have the primary goal of securing a safer, more efficient and more reliable electricity network.

One of the key projects presented during the Forum referred to the revolutionary Active Response trial for which TPS is providing the hardware platform through our award winning range of power converters that enable the creation of Soft Open Points on the distribution network. This project leads the way to efficiently managing spare network capacity that could save customers £271m and cut more than 448,000 tonnes of carbon emissions by 2030.

Building on the learnings that we have gained from the flagship Flexible Urban Networks (FUN-LV) project, as holders of a key role in Active Response we are now building a new generation of converters that will bring significant benefits to both the Low Voltage (LV) and Medium Voltage (MV) networks. This will lead to a better balance of power between substations to facilitate a higher adoption of low carbon technologies, such as the predicted increase in electric vehicles.

During his speech, Dr. Jakeman explained how the SOP converters works, what our initial power converters had achieved and how we are upgrading these devices to the next level for Active Response.

The main benefits that our next-generation converters will bring to the LV Network can be summarised into:

  • Silent operation due to faster switching
  • Continuous Rating increased by 60%.
  • Electrical Losses halved
  • Forced cooling near eliminated
  • Single sided access to reduce pavement utilisation and enable ease of service, more space efficient

The enabler for the above benefits is Silicon Carbide Semiconductor Switching technology which we are utilising in this project.

At MV level, we are building a Soft Power Bridge (SPB) which will have the same functionality as the LV SOP, however utilising a different architecture to deliver meshing capability at 11kV. To create a commercially viable solution for MV networks, Silicon Carbide comes into play once again for same reasons as for LV: noise, size and loss reduction.

Listen to Dr. Jakeman below to understand more about our next-gen power converters and how we are improving our solutions to better suit the requirements of today’s network:

TPS enters E-LOBSTER consortium to enhance distribution grid stability and reduce electricity losses in Railway networks and Power distribution networks

E-LOBSTER - connecting railway network, electricity grid and EV

Have you ever imagined connecting Railways, Electric Vehicles Chargers, Solar Photovoltaic Cells, Storage Systems and the Electricity Grid?

Well…. TPS and its partners did it!

The entire world is trying to develop more efficient, reliable and greener energy systems and, at the same time, cope with an increasing demand for power.

In addition, the use of Renewable Energy Sources (RES) is increasing rapidly and, despite the positive impacts, the introduction of these new power flows on the grid is challenging under the current network configuration. To overcome this, the European Electricity Distribution Network Operators (DNOs) and Light-Railway networks are independently developing several programmes. Through these schemes, they are targeting electricity loss reductions, cost optimizations, grid stability control while upholding the demands of Electric Vehicles (EV), energy storage systems and prosumers.

Given this background, a new consortium has emerged to support the combination of all those needs in a project called E-LOBSTER. The name stands for “Electric LOsses Balancing through integrated STorage and power Electronics towards increased synergy between Railways and electricity distribution networks”. Within this consortium, TPS will once again collaborate with Newcastle University and 7 other members: RINA, Rail Safety and Standards Board (RSSB), The University of Birmingham, Lithium Balance, Metro de Madrid, Spanish Railways Foundation (FFE) and The International Association of Public Transport (UITP).

This project intends to create an economically viable and easily replicable Transport-Grid Inter-Connection System that will establish synergies between three main players within the Energy and Transport sectors:

– Electrified urban transport networks (metro, trams, light railways etc.)
– Power distribution networks
– EV charging stations

Creating a connection between these players will enhance distribution grid stability through the inter-exchange of electricity and will lead to a much lower requirement for network reinforcements or upgrades. The enabler to deliver the objectives of the E-LOBSTER project is the use of smart Power Electronic Converters supplied by TPS. This solution will operate under an integrated Railway and Grid Management System which will optimize the capacity of both networks by improving the exchange of electricity between them, while supporting local RES self-consumption.

TPS’ role within this project will be to design, manufacture, deliver and test prototypes of Power Electronic Converters to facilitate resource sharing between the Electricity Distribution and Railway networks, aiming to achieve an integrated system.

E-LOBSTER will demonstrate the functionality of this new system in a real underground railway in Madrid. The railway would be connected to a local power distribution network with a high penetration of RES. The knowledge generated from the project will be further examined with the purpose of developing a superior design for a full-scale system, paving the way towards replication across the EU.

The project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 774392.
Dr. Nigel Jakeman, TPS Engineering & Business Development Director, commented:

“Another great success for TPS, enabling us to further build on the benefits of our family of Smart Grid Converters. On this occasion, we are using our awards-winning Power Electronic Converters in an application that can benefit both Distribution Network Operators and Rail Operators alike. Other projects where we have used our Smart Converters are Renewable Traction Power and Flexible Urban Networks. We’re looking forward to working with our partners and demonstrating this truly novel and value adding system.”
