Abstract
MCU () determines whether at least one of double three-phase inverter () or battery () has a failure, or battery () is fully charged, and switches control to be performed in inverter () between all-phase shut off and three-phase short circuit based on a motor rotation speed of double three-phase motor () when MCU () determines that any one of inverter () and battery () has a failure, or battery () is fully charged. Battery () and inverter () can be protected when current is inhibited from flowing from motor () to battery () due to a failure of inverter () or battery ().
