The buck converter circuit may include a first inductor, a smoothing capacitor coupled to the first inductor, a rectifier diode coupled in parallel with the first inductor and the smoothing capacitor, a control switch coupled to the first inductor, a control circuit configured to turn the control switch off and on repeatedly at a high frequency rate; and a snubber network coupled to the first inductor and the control circuit. The snubber network may include second and third inductors connected in series, wherein one terminal of the first inductor is connected to a node connecting the second and third inductors, and an auxiliary switch connected to the control circuit. A first terminal of the second inductor that is not connected to the node may be coupled to the control switch, and a first terminal of the third inductor that is not connected to the node may be coupled to the auxiliary switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zero-voltage switching buck converter and control circuit therefor","description":"A zero-voltage switching buck converter circuit and control circuit are provided.
