Abstract:
An inverter driving method for driving in parallel a plurality of inverters comprising the steps of:each of said plurality of invertersconverting a DC voltage into a first AC voltage,outputting, from a secondary side of a step-up device, a drive AC voltage obtained by stepping up said first AC voltage applied to a primary side of said step-up device, said primary side of said step-up device being driven with said first AC voltage; anddriving one of a plurality of loads in parallel by said drive AC voltage outputted from said secondary side of said step-up device,wherein said drive AC voltages outputted from said secondary side of corresponding ones of said step-up devices are controlled at a constant value, and respective drive frequencies of said plurality of inverters are controlled to have the same value.
