TīmeklisFingerprint Abstract The asymmetrical half-bridge (AHB) flyback converter is capable to achieve zero voltage switching (ZVS) and has lower voltage stress compared to the active clamp flyback converter (ACF). This topology gives much margin for components selection and transformer turns ratio design.
