Weblosses compared to a standard flyback operating in DCM. Furthermore, even with ZVS turn-on the switching losses will be higher than a hard-switching DCM operation because the frequency foldback cannot be implemented if the magnetizing current is in CCM. Therefore, an optional transition from active clamp WebAug 5, 2014 · During soft switching the voltage falls to zero (rather than just a minimum) before the MOSFET is turned on or off, eliminating any overlap between voltage and current and minimizing losses. (The technique can also be used to switch the MOSFET when current, rather than voltage, reaches zero. This is known as Zero Current Switching …

WebSep 3, 2024 · Your father’s Active Clamp Flyback concept was born and thereafter virtually eliminated clamping and switching losses. Changes since then have involved increasing switching frequencies from around 2 kHz to 500 kHz and higher. This was made possible mostly due to device improvements, packaging advances, and reduced size requirements.
