In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and ...

Measuring tiny differences in high-voltage circuits usually requires specialized differential test probes, which are often expensive. Fortunately, it’s possible to build your own high-voltage probe ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
