which was traced down to a dead electrolytic filter capacitor after days of crowd-sourced reverse-engineering and creating the first complete Centurion power supply schematic in probably many decades.

Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

This circuit prevents us from making power supply errors, using a different cable for each single output voltage. Let’s see how the PSU works.

Capacitors with unique construction and failure modes are placed on the AC line to manage EMI modes and ensure user safety.

A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...
