Abstract
The present invention provides a synchronous rectification converter circuit, including three transformer secondary-windings, three current transformer, a synchronous rectification switching unit, a diode rectification unit, and a control unit. Each of three current transformers includes a primary-winding and secondary-winding. The three transformer secondary-windings and the three current transformer primary-windings are alternately connected in series to form a first triangular structure. Three vertices of the first triangular structure are connected to the synchronous rectification switching unit. The three current transformer secondary-windings are connected in series to form a second triangular structure. Three vertices of the second triangular structure are connected to the diode rectification unit. The diode rectification unit is connected to the control unit and the synchronous rectification switching unit is connected to the control unit. The present invention achieves a purpose of precisely controlling the on-off state of the synchronous rectification circuit.
