Abstract
An inductor current reconstruction circuit of a power converter can include: a switching current sampling circuit configured to acquire at least one of a current flowing through a main power transistor and a current flowing through a rectifier transistor to generate a switching current sampling signal; an inductor current generating circuit configured to generate a reconstruction signal representing an inductor current in one complete switching cycle; and where the reconstruction signal comprises the switching current sampling signal and a current analog signal generated according to the switching current sampling signal and an inductor voltage signal representing a voltage across an inductor in the power converter.
