<p>This inverter device is equipped with: a switching circuit comprising multiple upper and lower arms; and a control unit for driving the switching circuit by means of a PWM modulation scheme. Switching components that constitute an upper-arm-side switching circuit and switching components that constitute a lower-arm-side switching circuit are composed of switching components of different types. The control unit shifts an average output voltage to the lower voltage side or to the higher voltage side with respect to the intermediate voltage of a source voltage supplied to the switching circuit on the basis of a condition that determines the magnitude relationship between on-resistances of the switching components that constitute the lower-arm-side switching circuit and on-resistances of the switching components that constitute the upper-arm-side switching circuit.</p> |
