Hi,
I am looking for a FET which would help me in controlling a 220V ac signal using a 0-5 V analog signal. i dont know of any transistors with such characteristics.
i thought of doing this by first using a transformer to bring the 220 down to some reasonable value, then pass it through the FET and then pass the signal again through a similar transformer. But all this seems a bit too redundant. there has to be a simpler way to it, i am sure.
i also thought of using a relay but that wouldnt do at all because i need the output as a function of my input.
i guess all i need is a voltage controlled potentiometre but that 220V ac is confusing me.
Could anyone help.
