Abstract:
A bridge circuit converts input direct-current voltage and outputs alternating-current voltage. A filter circuit attenuates a high-frequency component of the alternating-current voltage output from the bridge circuit. A clamping circuit is disposed between the bridge circuit and the filter circuit, and is capable of short-circuiting the output side of the bridge circuit. A control circuit has a first mode in which a switching element causes the alternating-current voltage to be output to the filter circuit at three or more voltage levels, and a second mode in which the switching element causes the alternating-current voltage to be output to the filter circuit at two voltage levels. When power conversion devices have their alternating-current side output paths connected and operate in parallel, at least one of the power conversion devices operating in parallel operates in the second mode.

Claim (Index 8):
A power conversion system, comprising:\n a first power conversion device; and a second power conversion device, wherein the first power conversion device and the second power conversion device have alternating-current side output paths that are connected, and operate in parallel, the first power conversion device includes:\n a first bridge circuit capable of converting input direct-current voltage and outputting alternating-current voltage; \n a first filter circuit that attenuates a high-frequency component of the alternating-current voltage output by the first bridge circuit; and \n a clamping circuit disposed between the first bridge circuit and the first filter circuit, and capable of short-circuiting an output side of the first bridge circuit, \n the first bridge circuit and the clamping circuit operate to output the alternating-current voltage to the first filter circuit at three or more voltage levels, and the second power conversion device includes:\n a second bridge circuit capable of converting input direct-current voltage and outputting alternating-current voltage at two voltage levels; and \n a second filter circuit that attenuates a high-frequency component of the alternating-current voltage output by the second bridge circuit.
