Abstract

PURPOSE:To improve the reliability of an inverter apparatus by supplying currents to respective loads through independent inverters, and providing an output switching thyristor switch which supports a normal inverter in case that one of the inverters malfunctions. CONSTITUTION:This apparatus is composed that supply electric powers of inverters 1, 2 are individually supplied through high speed thyristor switches 11, 12 to respective loads 31, 32, and a pair of inverters correspond to the loads of the respective systems. A low speed thyristor switch 41 for supporting the load connected to the inverter which might malfunction through a normal inverter is provided between power supply lines to the loads of the system.
