Beschreibung
Zusammenfassung:	The invention discloses a Buck circuit based on soft switching. The Buck circuit comprises a Buck circuit main body composed of a first switching tube, a main inductor, a main capacitor and a first diode; an inductor branch composed of a second inductor and a second diode connected with the second inductor in series, wherein the second diode limits current to flow from the first end of the inductor branch to the second end; a third diode, of which the cathode is connected with the first end of the inductor branch, and the anode is connected with the second end of the inductor branch; and a second capacitor. When the first end of the second capacitor is connected with the second end of the first switching tube, and the second end of the second capacitor is connected with the first end of the inductor branch; and when the first end of the inductor branch is connected with the second end of the first switching tube, the first end of the second capacitor is connected with the second end ofthe inductor branch.
