Abstract

PURPOSE: To prevent useless discharge of a battery due to erroneous operation, by employing a judgement result of existence of load current as one operating condition of an inverter thereby eliminating a start switch.
CONSTITUTION: Power is outputted from a commercial power source through a direct feed circuit 3 and a switcher 40, while simultaneously it ia fed through a recharger 10 to a battery 20. The switcher 40 is switched upon occurrence of power interruption, and power is fed from the battery 20 through an inverter 30 and the switcher 40. A current detector 50 is arranged at the output side, and the current detected through the current detector 50 is employed as one operating condition of the inverter 30. Consequently, the inverter can be started during power interruption only when current flows through an AC output 2.
