Abstract

See full text

The present disclosure provides a circuit control method and a circuit control apparatus, which are applied to a hybrid flyback circuit. The method includes: determining an acquisition time point according to a turn-on alternating duration of a first MOS switch and a second MOS switch on a main side of the hybrid flyback circuit and a preset time coefficient; acquiring a midpoint voltage between the first MOS switch and the second MOS switch according to the acquisition time point to obtain a first voltage signal; and adjusting negative excitation current in the hybrid flyback circuit according to a comparison result of the first voltage signal and a preset voltage value, so that the negative excitation current meets zero voltage switching of a primary-side switch of the hybrid flyback circuit.
