SMPS Journey continues...


Last week I was working on high voltage, high power SMPS using the push-pull topology. It worked well as I could charge a 2mF capacitor to 375V in about 5s. Later I had the urge to try out another design based on flyback topology. It manages to achieved the same thing but with simpler setup. The main difference I noticed is that the transformer is now warm whereas in the push-pull topology, the transformer show no temperature rise at all...

Now.... what am I gonna use them for... hmmm....
