Abstract

PURPOSE: To eliminate a short-circuit between power sources and to load a rush current at the time of start to a commercial power source by using the commercial power source at the time of start of a load by bringing the phase angles of the power sources in coincidence when an inverter power source is switched to the commercial power source.
CONSTITUTION: A phase detector 11 detects the phase angle of power supplied from a commercial power source 8. A switch 9 is so operated by a controller 10 that the phase angle detected by the detector 11 coincides with that of the power output from an inverter power source. Thus, when the phase angle of the inverter power source is in phase with that of the power source 8, the power sources are switched, and a damage due to the short-circuit of the power can be prevented. A timer T counts for a predetermined period of time to output a signal during the counting. The switch 9 connects a load 1 directly to the power source 8 on the basis of the signal. The controller 10 starts counting by the timer T at the time of start of the load 1, and connects the load 1 to the inverter power source when the counting is finished. Thus, since the power is supplied from the power source 8 to the load at the time of start of supplying power to the load 1, the load of a starting current can depend upon the power source 8.
