A ELECTRIC POWER REGENERATION APPARATUS THAT EQUIPPED A ACTIVE POWER FILTER IN ELECTRIC TRAIN

摘要

The present invention can increase the frequency of the actual transformer output without increasing the power consumption due to the switching loss of the inverter by connecting the inverter of comparatively low frequency to the DC feeder line in parallel and connecting the high voltage transformer to the transmission line, The present invention also provides an electric power regenerating apparatus for an electric vehicle system having an active power filter function capable of improving the control performance of an electric power filter function by obtaining an AC waveform close to that of an AC power source.;The DC power supply line is connected to the DC power supply line of the electric train in parallel with each other, and the DC power supplied from the DC power supply line of the electric motor is used as a switching pulse having an AC component having a switching frequency higher than its own switching frequency, A first and a second inverter for outputting an output signal; And a first and a second grid-connected transformer for summing the outputs of the first and second inverters and outputting them to an AC power line.;Electric vehicle, power regeneration, inverter, APF (active power filter)
