Abstract:
A control device applied to a flyback converter including an auxiliary switch includes: an output voltage integrator, configured to integrate an output voltage of the flyback converter to obtain an amplitude of a negative magnetizing current of the flyback converter; and a comparator controller, configured to compare the obtained amplitude of the negative magnetizing current with a reference value, and turn off the auxiliary switch according to a comparison result. According to the present disclosure, it is able to achieve zero voltage switching of a primary-side switch of the flyback converter with variable outputs.

Claim (Index 20):
The control method according to  claim 14 , wherein achieving zero voltage switching of a primary-side power switch of the flyback converter comprises:\n achieving zero voltage switching of the primary-side power switch of the flyback converter via resonance of an magnetizing inductor and a parasitic capacitor in the flyback converter.
