    How to modify/ design error amplifier compensation circuit (with TL431) for variable flyback converter and make it stable.

    I bought a power supply adopter (old, used, made for some device) of 24v 4.5A (from 230vac mains). It is a fixed output psu. My intention is to make it a variable psu of 30v to <=5v (as low as possible, and continuously variable). Schematic (simplified) of its error-amp circuitry is attached...

    How PFC responds to Load power demand in SMPS (flyback) converter

    I tried to understand PFC in an SMPS voltage converter. I read from many websites but still confused very much about the following things. Situation: it’s an SMPS flyback (for example) converter, to output (for example) 24v dc to an inductive load of 100W (average). Input 230v AC mains 50Hz...

    PCB Review - 200V Flyback Converter

    Hello, I have a first draft of a 24VIN 200VOUT PCB and I would appreciate any feedback and suggestions, especially from anyone who has experience with switching power supply design. This is a two-layer board with a ground plane on the bottom layer. Some things that I considered while laying out...
