The power supply circuit includes a secondary side rectifying unit and a voltage output side. The active clamping circuit includes a clamping energy-storing unit, a feedback control unit and a synchronous buck converter. The clamping energy-storing unit clamps and stores a voltage spike to obtain an energy-storing voltage. The feedback control unit detects the energy-storing voltage and informs the synchronous buck converter of the energy-storing voltage. The synchronous buck converter receives the energy-storing voltage and adjusts the energy-storing voltage to obtain an adjusted voltage when the energy-storing voltage is greater than a predetermined voltage. The synchronous buck converter sends the adjusted voltage to the voltage output side."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply apparatus with active clamping circuit","description":"A power supply apparatus includes a power supply circuit and an active clamping circuit.
