Abstract
An inductive current simulation circuit of a switching circuit, an inductive current simulation method of the switching circuit, and a switched-mode power supply are provided. The inductive current simulation method includes the following steps: based on an error amplification circuit, performing, by the error amplification circuit, an error amplification on a first sampling signal representing a current of a synchronous rectifier and a second sampling signal representing an inductive current simulation signal when the synchronous rectifier is turned on to obtain an error amplification signal; and reconstructing an inductive current according to the error amplification signal when the synchronous rectifier is turned on and a first current when a main power transistor is turned on to obtain the inductive current simulation signal.
