dudes
I am constructing a power supply that will use a triac for voltage control.
This unit causes a sound like hissing or light frying on a am radio very near
the unit.
I wish to construct a filter to kill this interference off. I do not want to
purchase a ready made filter. I understand the unit should be in a shielded
minibox and the leads filtered. anyone have the circuit values for filter
chokes and capacitors to fix this problem .and where does one place the parts
? on the ac input ,ac output lines? on the wires to the triac[gate] or across
the whole assembly? The current flow will be 10-14 amps. Used on 240vac.
anyone actually succeed in doing something like this?
