Circuit and Method for Controlling Rectifier, and Circuit Including the Rectifier

A method for controlling a rectifier, wherein the rectifier comprises a transformer, an inductor coupled with a primary winding of the transformer in parallel, and at least one switching component coupled between a secondary winding of the transformer and an output of the rectifier, the method comprising:

• sensing a current flowing into a combination of the inductor and the primary winding of the transformer;
• generating an indication voltage, based on the sensed current;
• comparing the indication voltage and a reference voltage;
• and
• driving the at least one switching component, based on a result of comparing the indication voltage and the reference voltage.
