Abstract
The invention provides a conversion circuit for converting input voltage into output voltage, including: a full-wave rectifier circuit including first and second branches connected in parallel, and each including a secondary winding and a rectifier switch; a first switch branch connected to midpoint of the first branch, and including first to fourth switches connected in series; a first resonant unit connected between connection node of the first and second switches and midpoint of the second branch; a second resonant unit connected between connection node of the third and fourth switches and midpoint of the second branch; a first primary winding connected in series to the first resonant unit; and a capacitor connected between connection node of the second and third switches and midpoint of the second branch. The conversion circuit of the invention improves conversion efficiency while maintaining smaller voltage stress on switches.
