Build a 2000-watt controller for line-powered inductive and resistive loads
Driving a mains-powered load, be it inductive or resistive, invariably has to be done with care and attention to avoid dangerous situations. In this design the mains power part is isolated from the driver part by means of an optocoupler. The driver itself, free from MCUs and software, is controlled by a DC or PWM signal. The circuit can be used with loads up to 2000 watts.
