TPS wins contract with Bombardier Transportation (BT) to provide Auxiliary Power Supply units for London Underground (LU)

Auxiliary Power Supply

Bombardier Transportation (BT), Sweden has placed a multi-million pound order with TPS to provide Auxiliary Power Supply (APS) equipment for 680 cars of London Underground’s Central Line.

TPS’s scope is to design and supply a cutting edge, innovative, efficient and compact APS system that will enable BT to deliver a high-quality traction system for LU. The technology embedded in these Auxiliary Power Supply units will significantly improve energy efficiency of the trains and reduce the total cost of ownership for LU.

A pioneer in Rail Power Electronics, TPS have been awarded a multi-million pound contract by BT to design and supply a new APS system for Central Line’s fleet. The scope of work is to design, manufacture and supply APS equipment for 680 cars and this contract will run until 2024.

Housed in a compact, under-floor mounted enclosure, all APS components are naturally cooled and require minimum maintenance. The equipment is designed for increased availability and can withstand severe rail environment, such as extreme temperatures, space constraints and high vibration. TPS’ auxiliary power units are built with an intelligent monitoring system that records events and conditions sent by the control system. These units also come with portable test equipment software which enables the train maintainer to easily diagnose the system from their laptop.

The APS units also incorporate an innovative DC-DC Power Module using cutting edge Silicon Carbide (SiC) technology which can sustain much higher voltages and can be switched at a much higher frequency, hence equipment can be made smaller with improved reliability.

Carlos Neves, Chief Executive Officer of TPS, commented:

“I am extremely pleased that after 2 years of a true collaboration effort between TPS and Bombardier we won this significant project with London Underground. This contract proves that our sustainable investment on R&D in innovative technologies was adequate and allows us to fully demonstrate our capabilities. The long-term goal for TPS is to exceed expectations developing innovative and sustainable solutions that, in this case, will help BT and LU to reduce carbon footprint and minimise the energy used by the Tube network.”
