Classification: CPC H  Y | IPC H

Claim 1:
2. The control circuit of claim 1, wherein the primary-side control signal generator comprises:
a primary-side original turn-on signal generator configured to receive the feedback signal of the output voltage of the isolated power supply and generate a primary-side original turn-on signal indicating the first turn-on instant; and
an anti-shoot-through logic circuit configured to receive the primary-side original turn-on signal and the secondary-side transistor switch control signal and, if the second turn-on instant is later than the first turn-on instant, generate the primary-side transistor switch control signal from the secondary-side transistor switch control signal so that the turn-on instant for the primary-side transistor switch in a current period is not earlier than the second turn-on instant.
