バータとして運転することを特徴とする電力変換装置。A DC power supply that is capable of voltage control or has a current limiting function, an inverse conversion device that is configured of a semiconductor element that has a self-extinguishing function and converts DC power supplied from the DC power supply into AC power, and a grid interconnection switch. energizes a separate power source such as a commercial power supply connected to the inverter through a circuit, a circuit to which an oscillator output signal is applied and supplies on-pulses and off-pulses to the inverter, and a circuit that supplies the on-pulses. and a synchronous control circuit for generating pulses synchronized with the separate power supply, a power loss detection circuit for detecting a power outage, etc. of the separate power supply, and an output signal of the circuit is applied to generate a bypass pair pulse to the inverter. If the separate power supply is normal, the interconnection switch is closed, only on-pulses are supplied to the inverter, the inverter is operated as a separately excited inverter, and the inverter is operated as a separately excited inverter. When the power supply is lost, the reverse conversion device is operated in a bypass pair mode, and then the oscillator energizes the circuit that supplies the on-pulses and off-pulses to supply the on-pulses and off-pulses to the inverse conversion device. A power conversion device characterized in that it operates as a self-excited inverter.
