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...
The key part of any electronic device is the power supply. Any instability or malfunction of the power supply part causes the device to stop working or demonstrate weird behavior. In this article/video, I introduced an AC-to-DC flyback Switching power supply that converts 85V-260VAC to...
The most important part of any electronic device is the power supply section. Any instability or malfunction in this part causes the device to stop its operation or show weird behavior. In this article/video, I introduced an AC to DC Flyback Switching power supply that converts 220V-AC to 8V-DC...
Flyback is the most common circuit topology to build galvanically isolated AC to DC or DC to DC converters. Flyback circuit is cheap and relatively easy to manufacture, therefore nowadays the majority of home or industrial appliances are powered using AC to DC Flyback converters. In general, a...
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...
