摘要 PURPOSE:To reduce the pulsation of the crest value of a DC current waveform extremely by forming the crest value of the DC current waveform of an inverter in a waveform, in which a waveform obtained by single-phase full-wave rectifying an AC current waveform is switched, in the DC current waveform of the inverter. CONSTITUTION:An inverter controller 43 controls an inverter 4 so that input- output voltage and currents coincide with command values at the same time as the start/stop and power running/regenerative operation of the inverter 4 on the basis of a command from a driving controller 42. Consequently, a current detector 44 detecting the AC currents of the inverter 4, a current detector 45 detecting DC currents and a voltage detector 46 detecting the voltage of a secondary battery 1 are connected to the inverter controller 43. A command equipment 47 changes over a changeover switch 470 to the (a) side and forms the waveform of an AC current command in a sine wave when an electric vehicle is operated on the basis of a command from the driving controller 42, and changes over the changeover switch 470 to the (b) side and forms the waveform of the AC current command in a square wave at the time of charging by a single-phase distribution system.
