Abstract
PURPOSE: To improve the reliability by providing a circuit for deciding the fault of switch from the signal indicating the operational state of switch and the signal indicating that the current flowing through the switch exceeds over predetermined level.
CONSTITUTION: In order to detect the fault of AC switches ACSW1, ACSW2 in power source equipment where two inverters INV1 and INV2 are operated in paralll through AC switches ACSW1 and ACSW2, under current detecting circuits 10, 20, circuits 11, 21 for detecting the state whether AC switches ACSW1 and ACSW2 are functioning or not, and the circuits 13, 14 for deciding whether AC switch is in fault or not from said two signals are provided. Consequently from the conditions that the load current flowing through AC switch is below predetermined level and that AC switch is functioning, fault decision circuits 13, 14 can produce fault signals d, d'.
