Zusammenfassung:	PURPOSE:To quicken switching operation to an inverter voltage at the time of service interruption by charging the output capacitor of a voltage doubler rectifier for multiplying and rectifying the output of an inverter, connected directly to a storage battery, from a commercial power source when commercial power is being received. CONSTITUTION:Output voltage of a first inverter circuit connected to a storage battery EB is multiplied and rectified by diodes D1, D2, and capacitors C1, C2. When commercial power is being received, the capacitors C1, C2 are charged with commercial voltage via diodes D3,...D6. Its charging voltage is 2Vac. Upon interruption of commercial power supply, the capacitors C1, C2 are forced to be charged with storage battery voltage Ei through a voltage doubler rectifier circuit. If 2Ei
