TRACTION CONVERTERS AND POWER ELECTRONICS

description

Traction Converter would have multiple line converters which convert single phase AC input to a stable DC link bus voltage. A combination of one or more inverters converts this DC bus voltage to 3-phase power controlling one or more traction motors each.

Traction converters also controls the slip-slide action of the wheels, harmonic correction in line side. Traction converter consists of Line side converter, DC Link and Series Resonance Capacitors, Inverters and Power Electronics cards (responsible for IGBT firing, monitoring and controlling of firing pulse)
