We’ve seen a number of people create plasma speakers over the years here at Hackaday, so at first blush, the latest Plasma Channel video from [Jay Bowles] might seem like more of the same. Even his ...

The RMR-xxx series are a sub-miniature 1W/2W toroidal SMD transformer designed for push-pull or full bridge topology transformer drivers, with isolation voltages from 1.5kVDC/min up to 4.5kVDC/min.

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

In the standard form of a flyback converter, the leakage inductance of the transformer creates a voltage spike on the drain of the primary field-effect transistor (FET). Preventing this spike from ...
