My first experience with soakage was a pleasant one, not like my first experience measuring a power transformer. When I was a teenager, a local “ham” operator (a mid-twentieth century term for an ...

The explosions of electrolytic capacitors is caused by applying the reverse voltage to the element (for it is a polarized element), thereby causing the dielectric layer to ...

The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

A perennial challenge in power-supply design is the safe and speedy discharge, or “dump,” at turn-off of the large amount of energy stored in the postrectification filter capacitors. This energy, CV 2 ...

This is the second in a two-part series looking at safety when experimenting with mains-voltage electronic equipment, including the voltages you might find derived from a mains supply but not ...
