US Patent 10483841 Motor vehicle

In a process of cancelling shutdown of a second converter during transmission of electric power between a first power line and a second power line with voltage conversion by a first converter in a shutdown state of the second converter, a motor vehicle performs single element switching control that switches one switching element between third and fourth switching elements of the second converter while setting the other switching element off, such as to prevent an electric current in a reverse direction to an electric current flowing in a first reactor of the first converter from flowing in a second reactor of the second converter.
