The O-Core toroidal power transformer cores enable the production of transformers that are 15% smaller in size and weight than traditional toroidal transformers. The cores use a silicon steel strip ...

Remember back…way back, to linear power supplies. Heavy transformers. Big capacitors. As part of my EDN CDEL build, I’ve decided to use just such a power supply as the front end to the two DC-DC PSU ...

I needed an inductor for a switch-mode power supply whose nominal inductance value would be 100 µHy. I knew of course that the actual inductance would be lessened as DC load current went up, but I ...
