An inventive isolated converter which exempts the auxiliary isolation devices with accurate voltage regulation is disclosed. The converter includes the primary side circuit with a primary controller controlling the on and off of the primary switch and a secondary side circuit with a secondary controller controlling the on and off of the secondary synchronous rectifier. The isolated converter uses the secondary controller to turn on the secondary synchronous rectifier after the secondary current decreases to zero to generate a negative tail current and turns off the secondary synchronous rectifier at a reference tail current peak value to generate a reflected negative current at the primary side circuit for turning on the primary switch.
