1. power conversion device comprises:

  • Pulse width modulation inverter (101) is used for alternating voltage is converted to the direct current phase voltage with three current potentials, and described three current potentials comprise positive potential, neutral point current potential and negative potential;

    A plurality of AC power (103) that are connected to three-phase load circuit (105);

    A plurality of power terminations, the output dc waveform of its synthetic inverter (101) makes dc waveform be similar to AC wave shape;

    AndCarry line, the neutral point that it is connected to three-phase load circuit (105) is used to transmit synthetic waveform.
