One method provides switching power conversion circuitry including an inductor and switches and clamp circuitry connected across the inductor. Control circuitry operates the switches and the clamp circuitry in a series of converter operating cycles which may include: (a) an energy transfer interval for transferring energy input to output via the inductor; (b) an energy recovery phase, during which the inductor current oscillates transitioning from substantially zero to a negative value, from the negative value to a positive value, and from the positive value toward zero; and (c) a clamp phase, during a portion of which the clamp circuitry is ON, energy is trapped in the inductor, the inductor current is negative, and is not zero at the end of the clamp phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zero voltage switching energy recovery control of discontinuous PWM switching power converters","description":"Buck and boost power converter topologies and methods of converting power are provided.
