A methodology, utilizing loop gain of circuitry to extract the main features for providing the useful indexes being able to come out the evaluation of light-load operation efficiency for power supply design, is proposed herein. A DC-to-DC converter scheme for adaptor application is adopted for demonstrating the relation between switching device conduction(More)
An inductance-based control strategy, for further optimize parameter design which is conducted through inductance adaptive variation on LLC resonant converter, is proposed. A simple switch concept is applied to set the desired magnetizing inductance, the main control factor, to achieve light load efficiency improving and overall required switching frequency(More)
