Abstract

PURPOSE:To effectively prevent the variation in the output power source by operating an inverter in synchronization with a commercial power when switching to a battery in emergency to supply power to a load. CONSTITUTION:A commercial power source 1 is connected through a transformer 2, a rectifier 4, a coil 5, and a changeover switch 8 to an inverter 9, and the output of the inverter 9 is supplied through a transformer 3 to a load. An operation signal having an output waveform always synchronized with the commercial power source 1 is obtained by a loop having an OR gate 12, a frequency divider 13, a phase detector 17, a comparator 27 and an OR gate 12. In other words, a loop in which the phase difference between the output of the power source 1 and the output of the divider 13 is converted to a pulse width and subtracted from the output of an oscillator 11 via the OR gate 12 is formed, thereby always producing the output waveform synchronized with the power source 1.
