Abstract
PURPOSE:To suppress such current in case of switching of power supply system by outputting after selecting either an odd numbered square wave or an even numbered square wave at an output selection circuit by an input phase detection circuit. CONSTITUTION:When electrical power failed after commercial power supply terminates at a form such as a negative wave form, pulse 18 generates immediately before the power failure, and an odd numbered wave form output terminal 29 of an output selection circuit 28 is permitted. At this time, a square wave 22 is outputted from a square wave generation circuit 21, and after this is divided by a two-phase split circuit 23, an odd numbered wave 24 is outputted to an output terminal 29 by the output selection circuit 28. The outputted odd numbered wave 24 is a derive.pulse of switching element of an inverter, and thus, the synchronized AC output is obtained from the inverter in case of power failure.
