The method includes: a secondary-side current signal of the half-bridge resonance converter is detected, and the detected secondary-side current signal is converted into a corresponding first sampling voltage signal; whether a cycle-by-cycle protection is required in accordance with the first sampling voltage signal is determined; and a driving signal of the half-bridge resonance converter is compulsorily blocked during a preset cycle, if the cycle-by-cycle protection is required. Short-circuit protection may be performed for the half-bridge resonance converter, meanwhile a power density of the half-bridge resonance converter is satisfied."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Short-circuit protection method and device for a half-bridge resonant converter","description":"Provided are a short-circuit protection method and device for a half-bridge resonance converter.
