The controller includes a power pin, a ground pin, a driving pin, a voltage sensing pin, and a loading voltage sensing pin, and is in collocation with a rectification unit, an inductor unit, a switch unit, an output unit, a voltage sensing unit, and a loading voltage sensing unit to implement a variable-frequency power control of power conversion. The controller performs one of the burst mode, valley switch mode, quasi-resonance (QR) mode, conduction mode, and peak loading mode based on a wide range of loading level. In particular, the loading level covered by the present invention includes the ultra-light, light, middle, full, and over-heavy loading, and the features of power saving, low switching loss, operation safety are thus achieved. Further, any over design employed to meet the wide range of loading level is prevented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable-frequency power controller","description":"Disclosed is a variable-frequency power controller.
