Claim 3:
4. The control circuit of claim 2, wherein the secondary-side transistor switch control signal is an electrical level signal, and wherein the anti-shoot-through logic circuit comprises a first logic gate comprising a first input, a second input and an output, the first input configured to receive the primary-side original turn-on signal, the second input configured to receive an inverted version of the secondary-side transistor switch control signal and, if the primary-side original turn-on signal indicates to turn on the primary-side transistor switch and the secondary-side transistor switch control signal indicates the arrival of the turn-off instant of the secondary-side synchronous rectification transistor, output a turn-on instant signal of the primary-side transistor switch indicating the arrival of the turn-on instant for the primary-side transistor switch.
