Abstract: An inverter device includes a converter circuit and a filter. The converter circuit converts a DC input voltage into an AC intermediate voltage based on six control signals, and includes first and second converters. Each of the first and second converters includes three switches, two diodes and a coupled inductor circuit. The switches of the first converter operate respectively based on three of the control signals. The switches of the second converter operate respectively based on the other three of the control signals. The filter filters the AC intermediate voltage to generate an AC output voltage.
