Abstract
The power correction method corrects transmitted power, which is transmitted between a primary side circuit and a secondary side circuit which is connected to the primary side circuit via a reactor and magnetically coupled with the primary side circuit via a transformer and is adjusted according to a phase difference between switching of the primary side circuit and switching of the secondary side circuit. The method includes a switching step of turning on first transistor and second transistor; a voltage applying step of applying a predetermined voltage; a switching step of turning on a third transistor and a fourth transistor; a delay time measurement step of measuring delay time; a slope measurement step of measuring slope of the current; and a correction step of correcting the transmitted power.
