I have been considering making a dimmer as the first of many projects to come. Searching google I have found quite a few good references. I understand that a inductor (choke) capacitor pair reduces the EMI caused by the rise time of the "firing angle". The problem I am having is in how do I size the choke instead of using a value between a max and min range and adjusting accordingly. Looking for a point in the right direction. Thanks in advance Just a thought would this be along the lines of LC filtering in power supplies!
