PROVIDING ON-BOARD POWER
Turbo Power Systems has developed Auxiliary Power Supply (APS) units for London Underground’s Central Line fleet on behalf of Bombardier, which will be utilised to service on-board equipment. The APS units incorporate an innovative DC-DC power module using silicon carbide 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.
