Extremely high current in super simple SMPS Flyback
Alright, I have found the mistake. As easy as it is... it was the lack of filtering at the input that was making indicators on lab benh powe supply going crazy. As soon as I add large 470uF capacitor …

Extremely high current in super simple SMPS Flyback
I'm building an SMPS in flyback topology. In order to do it, I use UC3845CB IC. In first step, I wanted to see if it even works at all with pulse transformer that I bought, made especially for flyback …

Switching power supply simulation problem
I'm building a 5V power supply using MC34063 IC. Before I build a prototype, I want to simulate it in Proteus to see if everything works correctly. Here is the schematic:
It is done according to the …
