Abstract:
A control device of a power converter includes first and second switching circuits. The device converts AC power supplied from an AC power supply into DC power, and supplies the DC power to the DC circuit. First converter arms are connected in series in the first switching circuit. Second converter arms are connected in series in the second switching circuit. The device further includes first and second control circuits connected to the first and the second switching circuits and control gate pulses of each of the first and the second arms respectively. A first and a second power interruption compensation circuits supply power to the first and the second control circuits for prescribed durations in power interruptions of the first and the second control circuits respectively.

Claim (Index 7):
A control device of a power conversion device converting alternating current power into direct current power and supplying the direct current power to a direct current circuit, the alternating current power being supplied from an alternating current power supply, the power conversion device being separately-excited and including a first switching circuit and a second switching circuit, the first switching circuit including a plurality of first converter arms connected in series, the second switching circuit including a plurality of second converter arms connected in series, one end of the first switching circuit and one end of the second switching circuit being connected to a high-voltage side of the direct current circuit, another end of the first switching circuit and another end of the second switching circuit being connected to a low-voltage side of the direct current circuit, the control device of the power conversion device comprising:\n a first control circuit controlling an on-timing of each of the plurality of first converter arms connected to the first switching circuit; a second control circuit controlling an on-timing of each of the plurality of second converter arms connected to the second switching circuit; and a higher-level control circuit connected to each of the first control circuit and the second control circuit, when a failure of the first control circuit is sensed, the higher-level control circuit outputs, to the second control circuit, a bypass pair command causing a bypass pair state by using the second switching circuit, when a failure of the second control circuit is sensed, the higher-level control circuit outputs, to the first control circuit, a bypass pair command causing a bypass pair state by using the first switching circuit.
