TPS’ revolutionary 3 in 1 technology – powering electro-diesel trains! A highly flexible and scalable power conversion solution

TPS - new APUs to Brush Traction Class 769 Flex trains

Another important win for TPS this year! We have been awarded a new contract by Brush Traction (A Wabtec company) to deliver Auxiliary Power Supply Units (APS) for the newly refurbished GWR fleet of Class 769 Flex trains owned by Porterbrook.

These trains will run on both electrified & non-electrified routes, operating on Heathrow Express services and between Reading – Gatwick.

The solution provided by TPS is designed to meet the requirements for tri-mode operation, this way allowing the train to use power from three different sources:

– Diesel-alternator set
– Third rail
– Overhead line equipment

This innovative technology is primarily designed to provide power for existing equipment and also for the new Air-Conditioning (HVAC) units. Our solution can lead to significant savings and, potentially, a Lower Carbon Footprint for the operator.

Focused on providing high levels of efficiency, the Auxiliary Power Supply Units (APS) designed by TPS will be configured for a motor alternator replacement application, using power from either one of the three sources. These APS units will then filter any fluctuations in the power sources and will provide a clean electricity supply to the equipment on the train.

Our APS unit within these trains presents a series of advantages, some of which include: a higher flexibility in operation, increased reliability and a robust design which can endure severe rail environment and space constraints. Our APS units are manufactured using a technology that allows the magnetic components to be significantly reduced in size and weight, this way allowing our auxiliary power units to be mounted in a single underfloor enclosure.

Other key benefits associated with these systems include high conversion efficiency at which they operate, and this greatly reduces the equipment’s power losses, leading to a greener power conversion solution. These APS units also include an intelligent monitoring system which records events and conditions reported by the system.

In recent years many changes and challenges have been shaping the rail industry, some of which relate to urban growth, digitalisation, the need for high-speed transport and the different energy sources designed to power trains. Here at TPS our highly experienced team are constantly innovating and gracefully embracing these challenges by designing and incorporating cutting-edge technologies into our products. TPS has a pedigree of successfully developing APS units for rolling stock platforms for more than 30 years.

Building on the success of our fruitful relationship wih Wabtec, this new project represents an important milestone in our ongoing collaboration and shows that our expertise in delivering highly reliable and efficient power conversion systems is key to developing best-in-class solutions for the rail industry.

Carlos Neves, Chief Executive Officer, commented:

I am extremely pleased that after many years of successfully collaborating with Wabtec on several projects, we have now won this promising new contract with Brush Traction. We are confident that this contract is only the beginning of a rewarding partnership. We aim to fully demonstrate our capabilities by delivering an innovative and sustainable solution which will help Brush Traction to reduce carbon footprint and save costs.

Accolade for TPS at the Railway Industry Innovation Awards 2018

Turbo Power Systems (TPS) has received a highly commended certificate in the Environment Category at the Railway Industry Innovation Awards 2018. This certificate was received for TPS’s ground-breaking and ultra-efficient DC-DC Power Module.

The Rolling Stock (railway vehicle) market is craving for compact, light-weight, reliable, efficient and greener power conversion systems. To this effect, TPS’s DC-DC module was designed to develop the next generation of innovative power conversion equipment that will achieve all the above-mentioned goals.

One of the main power conversion equipment in the rail vehicle is an Auxiliary Power Supply Unit (APU). TPS has been designing these APUs for over 30 years and its core objective is to solve the power conversion needs of other equipment installed on board a rail vehicle.

TPS’s APU unit consists of three stages namely the input stage, the conversion stage, and the output stage. They are designed to take voltage from multiple power sources such as overhead line, 3rd rail, diesel-electric engine and batteries. Once these sources are connected, the APUs convert them to a stable and clean supply for use by on-board and utility equipment such as air conditioning compressors, brake compressors, lighting, passenger information systems, at seat sockets, microwave, fridge etc.

TPS’s DC-DC Power Module is designed using cutting-edge Silicon Carbide (SiC) components and is incorporated into the input stage of the APU. These SiC components operate at a higher switching frequency than standard silicon components resulting in size and weight reductions and reduced losses (i.e. higher efficiency). The DC-DC Power Module also provide galvanic isolation between input and output supply thereby ensuring protection for other equipment within the environment.

There are very few companies that are at the forefront of research in the application of SiCs and TPS will be one of the pioneers to effectively use this technology for the Rolling Stock market.

The applications for this DC-DC technology is multi-faceted and can be used in Transportation and Energy markets in the form of power converters, electric vehicle chargers, battery chargers, photovoltaic systems and isolated power transfer for electricity distribution.

As we continuously strive to exceed expectations by developing innovative and sustainable solutions, being highly commended is a recognition of TPS’s credibility and efforts in the power electronics field.

Other awards and shortlists for DC-DC Power Module were in prestigious events such as Elektra Awards 2016 and UKRIA 2018.
