I made dimmer circuit, used as heating element control, like this one. Also I used
around 35uH choke 16A. When I turned on the circuit this buzzing noise
came from the circuit and the element. So I turned it off, took the choke
off and the noise came only from the element but small noise came from
the circuit. I used radio to listen to statics which came from the control and
it seems that without the choke the static decreased.
Can anyone tell me what I can do? Regulation in my country says I have
to eliminate both RFI and EMI.
