Discharge filter capacitors
WebJul 5, 2001 · 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 /2, can usually reach tens of joules. If you let the capacitors self-discharge, dangerous voltages can persist on unloaded electrolytic ... http://www.electronicrepairguide.com/capacitor-discharge.html

WebAnother way of discharging a capacitor is through the use of a lightbulb. Simply take a 100W light bulb and screw it into a bulb socket with wires. Attach one wire to each of the … WebSeveral manufacturers make ICs designed specifically to discharge the capacitors. The TEA1078 (made by NXP) is one example, but it's by no means alone. In case you were wondering, no, you can't use this IC to discharge big filter capacitors - it's designed to reduce the voltage across a 330nF X2 capacitor to less than 60V in under 300ms.
WebOver time, the capacitor will discharge through R to the point where the SCR turns off, and this subsequently closes the transistor and the uC detects this to perform some action. When R = 100kohm, it takes about 6 minutes for the cap to discharge and all the other stuff in the micro to start. When R = 120kohm, the cap does not discharge at all ...
