LLC resonant converter utilizing a step‐gap transformer structure for holdup time improvement

Summary This letter presents a current‐controlled variable magnetizing inductance of transformer for further improving the holdup time on half‐bridge LLC converter. When the input voltage is failed, the magnetizing inductance of transformer can be decreased sharply; therefore, the LLC converter hold...
