Abstract: A synchronous rectification converter circuit is provided, including three transformer secondary-windings, three current transformers, a synchronous rectification switching circuit, a diode rectification circuit, and a control circuit. 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 circuit. Three vertices of the first triangular structure circuit are connected to the synchronous rectification switching circuit. The three current transformer secondary-windings are connected in series to form a second triangular structure circuit. Three vertices of the second triangular structure circuit are connected to the diode rectification circuit. The diode rectification circuit is connected to the control circuit and the synchronous rectification switching circuit is connected to the control circuit.
