Abstract
An inverter device (), including a first inverter (), and a second inverter () connected in parallel to the first inverter. Both the first and second inverters () are three-level inverters. The first and second inverters () generate first and second output voltages (V, V) using the voltage (Vc) at the connection point between a first capacitor (C) and a second capacitor (C) connected in series and evenly allocating a power supply voltage (Vin). A control circuit () duty-controls the second inverter at high frequency, when the second inverter () switches the level of the second output voltage (V).
