Abstract
An inverter controlling method comprising corresponding DC bus voltage after power inversion relating to commercial power supply voltage, and in a comparator, comparing both voltages, detecting the DC bus voltage at the time point when the both voltages are the same to discriminate and store the level of the commercial AC power supply voltage, and making correction of the output voltage at the next operational start of the inverter on the basis of the stored information.
