ABSTRACT:
A power circuit includes a transformer having a flyback winding for outputting an energy at an off-time of a primary winding to a secondary circuit a forward winding for outputting an energy at an on-time of the prime winding and a high voltage winding for outputting an energy over an entire period, a first rectifying circuit for rectifying the output of the flyback winding; a second rectifying circuit for rectifying the output of the forward winding, a voltage detection means for detecting the output voltage of the first rectifying circuit, first control means for controlling the on-time of the transformer in accordance with the output of the voltage detection means to control the output voltage of the first rectifying circuit to a predetermined value, and second control means for turning on and off the output voltage of the second rectifying circuit independently from the first control means.
