摘要： Provided is a bidirectional converter which has flexibility to be applicable in various conditions and performs stable switching of operation mode at high efficiency. An electronic device which supplies power in various conditions and operates with excellent efficiency is also provided. An electronic device is provided with a bidirectional converter, which has a reactor and four switches between power supply input terminals and a secondary battery, and a system circuit is supplied with an operation voltage through the bidirectional converter. A status signal indicating the operation status of the system circuit is transmitted to a microcomputer of the bidirectional converter, and based on the status signal, switching of operation mode of the bidirectional converter is controlled.
