Abstract
A circuit and a method for controlling a rectifier, and a circuit including the rectifier are disclosed. The rectifier may comprise: a transformer (T); an inductor (Lm) coupled with a primary winding (Np) of the transformer (T) in parallel; at least one switching component (SR, SR) coupled between a secondary winding (Ns, Ns) of the transformer (T) and an output of the rectifier. The method may comprise: sensing (S) a current flowing into a combination of the inductor (Lm) and the primary winding (Np) of the transformer (T); generating (S) an indication voltage, based on the sensed current; comparing (S) the indication voltage and a reference voltage; and driving (S) the at least one switching component (SR, SR), based on a comparison result of the indication voltage and the reference voltage. The timing point for turning on/off the switching component (SR, SR) may be optimized, so as to reduce the power loss and improve the efficiency.
