Web21 jan. 2024 · More specifically I have looked into an offline 240Vac (fairly low output power) flyback convertor recently. It became clear that as long as the transformer is well / appropriately designed the MOSFET switching losses dominate the design in terms of keeping the switching frequency low enough to have reasonably efficiency. The next step is to select the right MOSFET for the application. To do so, calculate the maximum current and voltage that the switch will have to withstand. Calculate the maximum voltage with Equation (3): Note that a 20% security margin has been added to VDS_MAXto ensure the converter’s safe … Meer weergeven There are many important design decisions and tradeoffs involved in designing a flyback converter.
