This paper presents dual-switch Quasi-Resonant (QR) flyback topology as a cost effective and reliable alternative to the LLC resonant converter for energy efficiency regulation. The proposed topology shows excellent efficiency performance, while maintaining simple design of the conventional flyback converters. It offers higher efficiency than LLC resonant converter at medium and light load, res...

The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in dc-dc conversion. This technology transfers bulk energy efficiently through a series-resonant circuit in the direct path of the energy transfer. This resonant converter forms a high-frequency ac link between the voltage sources connected to the input and output terminals. The...

High power factor, high frequency single stage single switch resonant inverter for the application of high frequency applications is presented in this paper. The power circuit is designed with a power factor corrector with single-switch current-fed high frequency resonant inverter. Number of switches used in conventional ballast circuits is reduced in single switch approach. SEPIC (Single ended...
