An inverter device includes: multiple inverters that switch input voltages by turning on and off respective switching elements to thereby apply excitation currents to primary excitation windings of respective boosting transformers and output alternating-current voltages from secondary output windings of the respective boosting transformers, the multiple inverters having the same output characteristics, and a common control circuit, on/off control of the switching elements of the inverters being performed by the same switching signal output from the common control circuit.
