| Abstract |
One of the most heavy electrical parts in a high power and high performance 3KV locomotive is the passive input filter that has to reduce the armonic contents of overhead line current according to the EMC with the signalling system. In this paper the authors explain how it is possible to reduce input filter weight and dimension using a combination of passive and active parts for a 3 KV, 6 MW inverter locomotive for Italian Railway. Special active filter topologie is designed to combine high voltage operation of 3 KV passive filter and low voltage of the high frequency IGBT PWM inverter included in the active one. Control techniques are explained and simulation results are shown. |
