Title:
ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/111497
Kind Code:
A1
Abstract:
According to the present invention, an inverter circuit comprises a plurality of flying capacitor circuits, each of which contains a plurality of switching elements and at least one capacitor, and converts a direct-current power that is inputted from a direct-current power supply into an alternating-current power. A control circuit 50 controls the plurality of switching elements. The control circuit 50 controls the plurality of switching elements so that the plurality of capacitors, which are contained in the plurality of flying capacitor circuits, are connected in series between both ends of the direct-current power supply when the plurality of capacitors are initially charged.
