Introduction/Abstract around the world about loweringElectronicVarious initiatives for system energy consumption are prompting single-phase AC inputpower supplyDesigners use more advanced power technology. To achieve higher power levels, these initiatives require efficiencies of 87% and above.due to standardflybacktype (flyback) and dual switchPositiveThese high efficiency stages are not supported by traditional power topologies such assoft switchreplaced by resonant and quasi-resonant topologies. working […]
