Abstract
A system for operation of an induction stove includes an AC to DC voltage converter receiving AC voltage from a power input, a voltage sensing unit coupled to the converter and including an optocoupler, and a processor coupled to the sensing unit for receiving voltage information from the unit and controlling at least one of input voltage, input current, and oscillation frequency of a heating coil of the induction stove. A method for operating an induction stove includes converting an AC voltage from a power input to a DC voltage, supplying the DC voltage to a voltage sensing unit coupled to the converter and including an optocoupler, transmitting a voltage measurement from the sensing unit to a processor, and controlling at least one of an input voltage and oscillation frequency to a heating coil of the induction stove via the processor based at least in part on the voltage measurement.
