Abstract
A power conversion circuit includes a switching circuit, a resonant circuit, a rectifying circuit, a controller and a transformer including a primary winding and a secondary winding. The resonant circuit is electrically coupled to the switching circuit and the primary winding. The rectifying circuit is electrically coupled to the secondary winding. The controller is electrically coupled to the switching circuit and the rectifying circuit and configured to selectively output one of a frequency modulation signal and a pulse width modulation signal as a second control signal according to a working frequency of a first control signal.
