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 2):
The power conversion system according to  claim 1 , wherein\n the bridge circuit includes a first switching element and a second switching element connected in series, and a third switching element and a fourth switching element connected in series, both terminals of the first switching element and the second switching element and both terminals of the third switching element and the fourth switching element are connected in parallel to a direct-current power supply, the clamping circuit includes a fifth switching element and a sixth switching element connected in series and disposed oriented in opposite directions, in the first mode, when alternating-current voltage output from the filter circuit is positive, the second switching element and the third switching element are switched off, the sixth switching element is switched on, and (i) the first switching element and the fourth switching element and (ii) the fifth switching element are complementarily switched on and off, in the first mode, when the alternating-current voltage output from the filter circuit is negative, the first switching element and the fourth switching element are switched off, the fifth switching element is switched on, and (i) the second switching element and the third switching element and (ii) the sixth switching element are complementarily switched on and off, and in the second mode, the fifth switching element and the sixth switching element are switched off, and (i) the first switching element and the fourth switching element and (ii) the second switching element and the third switching element are complementarily switched on and off.
