Abstract
A control IC including a full-bridge circuit is disposed on a primary side and a secondary side. Bidirectional communication is performed between the primary side and the secondary side in a state in which they are isolated. A control signal output from the primary side or the secondary side earlier is preferentially processed. As a result, the authority to control a switching element can be freely given to a primary-side control IC or a secondary-side control IC, and any control processing can be performed with software.
