Abstract :
A new type of reversible traction substation is proposed and a small test of concept model was built and investigated. The test of concept consists of a 10 kVA three-phase IGBT inverter placed in anti-parallel with a 75 kVA three-phase diode rectifier. The inverter is not only capable of pumping energy back into the AC power supply during excessive regeneration, but also acts as dynamic power filtering (DPF) during normal traction load conditions. The total control algorithm for the inverter/DPF is implemented on a TMS320C31 digital signal processor (DSP)
