Discharging the capacitor

I want to discharge the capacitor very fastly (in less time).

I am using 100uf /450v electrolyte caps.

Please give some helpful suggestion on this i really need this urgently.

We need more details of what you are doing to give a proper answer.
For instance..
what voltage is the capacitor charged to ?

In L6562AD PFC ckt , 200uF/450v Electrolytic cap at the PFC o/p takes longer time to discharge when we switch OFF the mains in No load / no lamp condition. .

Switching on the mains while Cap is discharging gives high voltage spike and also hissing noise which may damage our HID ckt.

it charges cap at 450v .

i need strng suggestion on this.

Thanks for the reply

The usual method is a resistor and switch/relay of some kind.
The exact combination depends on such things as..

What voltage do the capacitors charge to (probably less than 450)
What voltage counts as discharged.
How long should the discharge take. (a faster discharge needs more powerful resistors)

If the on/ off switch, switches mains power it can probably be adapted to discharge the caps in the off position.

to discharge a capacitor use a breeding resistor by shorting the terminal of the capacitor with the resistor
