The power supply circuit includes a primary rectifier unit, a modulation unit, a transformer, a secondary rectifier and filtering unit, a current feedback unit and a current sampling control unit. The power supply circuit removes a liquid electrolytic capacitor at a primary side, and an output current of the power supply circuit has a periodically changing current value. The power supply circuit may determine when the output current is at a peak value based on a feedback voltage outputted by the current feedback unit, such that the power supply circuit may manage and control a size of the peak value of the output current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply circuit, power supply device and control method","description":"Provided are a power supply circuit, a power supply device and a control method.
