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 3):
The control device of the power conversion device according to  claim 2 , further comprising:\n a higher-level control circuit connected to each of the first control circuit, the second control circuit, and the third control circuit; a first abnormality detection circuit sensing an abnormality of the first control circuit; a second abnormality detection circuit sensing an abnormality of the second control circuit; and a third abnormality detection circuit sensing an abnormality of the third control circuit, when normal, the higher-level control circuit outputs, to the first control circuit, a phase control pulse of each of the plurality of first converter arms included in the first switching circuit, and outputs, to the second control circuit, a phase control pulse of each of the plurality of second converter arms included in the second switching circuit, and outputs, to the third control circuit, a phase control pulse of each of the plurality of third converter arms included in the third switching circuit, in the case where a signal is received from the first abnormality detection circuit, the higher-level control circuit stops the output of the phase control pulse to the first control circuit and outputs, to the second control circuit and the third control circuit, a bypass pair command causing a bypass pair state by using at least one of the second switching circuit or the third switching circuit, in the case where a signal is received from the second abnormality detection circuit, the higher-level control circuit stops the output of the phase control pulse to the second control circuit and outputs, to the first control circuit and the third control circuit, a bypass pair command causing a bypass pair state by using at least one of the first switching circuit or the third switching circuit, in the case where a signal is received from the third abnormality detection circuit, the higher-level control circuit stops the output of the phase control pulse to the third control circuit and outputs, to the first control circuit and the second control circuit, a bypass pair command causing a bypass pair state by using at least one of the first switching circuit or the second switching circuit.
