Hi,
Thanks for your help.I got one simple pwm power controller on discovercircuits.com . Can you help to tell me how to interface the ac chopper output and the pwm input ? The input and output should be AC voltage .I mean, the load has to be an ac load , not dc . The circuit input voltage is +6V, so should i first step down the voltage from the 240V supply to 6V before feeding the ac chopper ? The frequency has to be a fixed 50HZ.
Do you have any link where i can get an ac chopper schematic, using bidirectional switch ?
Thanks for your help .
