Hi,
I have a dimmer circuit that works by controlling the phase of the AC lamp, this is done with a triac.
I have read that mains supression is required, and i acheive this via a series toroidal dimmer supression choke in series with the lamp, and a X2 capacitor.
Some circuits i have seen use a 100uH choke, and a 150nF cap, others use 1mH chokes and 100nF cap.
How do i work out what value choke and cap i need ?
