Abstract

PURPOSE: To intend to improve the reliability, by making only control circufit to be operated during waiting, making the inverter to be operated for a constant time in each period, and monitoring the function.
CONSTITUTION: In an inverter 3, a control circuit 6 which gives gate control signal to the inverter 3 through block circuit 10, monitor 9 which monitors state of alternating current source, and a timer circuit 8 which output signal in each period are provided. Control circuit whose power loss is small is made to be operated during waiting of the inverter, furthermore, the inverter circuit is made to be operated for a constant time in each period by the timer circuit, this state is monitored by supervisory monitor 9, and the inverter is test-run periodically. From this, waiting operation loss at no load of the inverter can be reduced to 1/ several 10, compared with former value, and furthermore, the reliability can be improved by monitoring the function of the inverter periodically.
