Abstract
Disclosed are an isolated power converter and a switching control signal using the same. In the isolated power converter, the positions of the power switch and the primary winding are exchanged, and the feedback voltage detection and secondary current zero-crossing detection are carried out in accordance with the voltage across the primary winding. Thus, primary side control can still be implemented without employment of an auxiliary winding.
