The MPU calculates the present power value according to measured current and voltage signals, and compares the present power value with the required power of the host computer to change the set pulse width value of the PPG. When a magnetic energy conversion detecting circuit outputs an enabling signal, the PPG outputs the pulse signal with the setting pulse width to drive the IGBT and realize the regulation of power.
