Claim:
1. A power conversion device including a plurality of direct current power sources that converts an output voltage of each of the direct current power sources into an alternating current voltage, and outputs the converted alternating current voltage in series connection to an alternating current motor, the device comprising: a voltage converter connected to each of the direct current power sources to convert the output voltage of the direct current power sources and having a primary circuit and a secondary circuit insulated from each other by a transformer; a voltage controller that controls an output voltage of the each voltage converter; an inverter circuit provided on an output side of the voltage converter to convert the voltage output from the voltage converter into an alternating current voltage; and a voltage detector that detects an input voltage of the voltage converter, wherein the voltage controller,
