PROBLEM TO BE SOLVED: To provide a vehicle power conversion apparatus including an energy storage device and an energy consumption device which can continuously operate a dynamic brake regardless of the charging state of the energy storage device and avoid interference of the operations between the devices while maintaining the functions of the energy storage device and the energy consumption device.SOLUTION: A vehicle power conversion apparatus includes an inverter device which drives an AC motor by converting DC power obtained from a DC power source into three-phase AC power and an energy storage device on the DC side of the inverter device, and uses one of pieces of current control means on the high voltage side and the low voltage side constituting a chopper circuit as the current control means of an energy consumption device.SELECTED DRAWING: Figure 1
【課題】エネルギ蓄積装置とエネルギ消費装置を備えた車両用電力変換装置において、エネルギ蓄積装置の充電状態によらず発電ブレーキを連続して動作させることができ、エネルギ蓄積装置とエネルギ消費装置の機能を維持しながら装置間の動作の干渉を回避する。【解決手段】直流電源から得た直流電力を三相交流電力に変換して交流電動機を駆動するインバータ装置と、インバータ装置の直流側にエネルギ蓄積装置を備え、チョッパ回路を構成する高圧側または低圧側の電流制御手段の一方をエネルギ消費装置の電流制御手段として用いる。【選択図】図1
