Hi,
I am making a fan dimmer like the attached file dim2.jpg
When dimmer is at low speeds, you can hear a noise in the fan. I think I need to add a series choke and a parallel capacitor like the attached file dim1.jpg but I do not know how to calculate their values. Could you please give me an idea?
