I will try again to explain what I want to do. My induction PCB operates at 220/240 VAC which is applied at CN1 in my circuit. I want to convert to 110 VAC for the US market. I have no problem with the low voltage side of my circuit but I need assistance with the high voltage side.The induction coil which I use to heat metal instruments connects to CN2/CN3 in my circuit. When the instrument is inserted in the coil an eddy current is generated and heats it. This works fine with 220 volts but not for 110 volts. I need to know what components to change to get the same results as 220 V. I thought is was a simple matter of reducing the value of R1 and R4 to get the same VA at CN2 and CN3 but it turned out to be not that simple. I would appreciate your help.
