Abstract

An inverter device (1) including a first inverter (10) and a second inverter (20) connected in parallel to the first inverter. Both the first and second inverters (10 20) are three level inverters. The first and second inverters (10 20) generate first and second output voltages (V1 V2) using the voltage (Vc) at the connection point between a first capacitor (C1) and a second capacitor (C2) connected in series and evenly allocating a power supply voltage (Vin). A control circuit (40) duty controls the second inverter at high frequency when the second inverter (20) switches the level of the second output voltage (V2).
