Claim Text:
1. A power conversion apparatus comprising: a primary side circuit having a primary side first arm circuit and a primary side second arm circuit; a secondary side circuit magnetically coupled to the primary side circuit via a transformer, the secondary side circuit having a secondary side first arm circuit and a secondary side second arm circuit; and a control unit configured to increase a frequency of switching of each of the primary side circuit and the secondary side circuit 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 circuit and the secondary side circuit is increased, wherein the phase difference is a time lag between the switching timings of the primary side first arm circuit and the secondary side first arm circuit, and a time lag between the switching timings of the primary side second arm circuit and the secondary side second arm circuit, wherein the time lag between the switching timing of the primary side first arm circuit and the secondary side first arm circuit and the time lag between the switching timing of the primary side second arm circuit and the secondary side second arm circuit are controlled to be equal to each other.
