Abstract
An inverter device includes a source current calculator and an inverter circuit, wherein: the source current calculator calculates an average value of the DC bus current Ical during a PWM cycle through arithmetic operation executed based upon instantaneous values of the DC bus current Idc of the inverter circuit; and the source current calculator provides an estimated value by designating the average current value Ical during the PWM cycle as an input source current Isrc during the PWM cycle.
