Abstract
The present disclosure provides a forward converter with secondary LCD connected in series to realize excitation energy transfer, comprising a forward converter main circuit and an energy transfer and transmission circuit. The forward converter main circuit includes a high-frequency transformer T, a switching tube S, a diode D, a diode D, an inductance L, and a capacitor C. The energy transfer and transmission circuit includes a diode D, a capacitor C, and an inductance L. The circuit structure of the present disclosure has simple circuit structure and high reliability. And the reverse recovery problem of the diode could be eliminated by the soft switch-off or soft switch-on of the switching tube, which further reducing the loss of switching tube and diodes and improving the overall efficiency. In addition, the excitation energy could be transferred to the load side to improve the energy transmission efficiency.
