Abstract

A power conversion apparatus includes a primary side circuit and a secondary side circuit magnetically coupled to the primary side circuit via a transformer, and converts power between a primary side port of the primary side circuit and a secondary side port of the secondary side circuit, using switching of each of the primary side circuit and the secondary side circuit. The power conversion apparatus further includes a control unit that controls a frequency of the switching and a phase difference between the switching of the primary side circuit and the switching of the secondary side circuit such that power conversion efficiency between the primary side port and the secondary side port is increased.
