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.

Abstract: An inverter device includes a converter circuit and an output circuit. The converter circuit generates a DC intermediate voltage based on a DC input voltage from a power source. The converter circuit includes: a first inductor and a first switch that are coupled in series across the power source; a second switch and a second inductor that are coupled in series across the power source; and a diode and a capacitor that are coupled in series between a common node of the first inductor and the first switch and a common node of the second switch and the second inductor. The output circuit generates an AC output voltage based on the DC intermediate voltage across the capacitor.
