Abstract
PURPOSE:To suppress excess current at the time of switching a power source, by setting the output voltage of an inverter to be first voltage equal to or lower than second line voltage, when power is switched to a first power source from a second power source. CONSTITUTION:An inverter section is composed of a DC power source 1 and an inverter circuit 4, and an AC filter 5 connected to the output, and the output of the filter 5 and a by-pass power source(a second power source)10 are connected to a by-pass change-over circuit(a power switching means) 8, and by by-pass switching command, an inverter(a first power source) and the by-pass power source 10 are switched to each other, and current is fed to a load 11. The inverter circuit 4 is controlled by a PWM controlling circuit 12. When said first and second power sources are switched and current is fed, then inverter output voltage is set to be first voltage equal to or lower than the voltage of the second power source 10, and is changed from the first voltage to specified voltage for a specified time, and the output voltage of the inverter is controlled.
