Abstract: An implementation of a digital circuit that measures, in real time, the output power of medium-frequency (25–50 kHz) induction-heated cooking appliances, maintains and controls the power through GSM and potentiometer. The voltage and current are sensed using analog-to-digital converters that are inbuilt in Pic18. The power-measuring algorithm is very simple while maintaining good accuracy. We multiply the sensed current and voltage values and average them to calculate the average power. Maintaining power is done through the relay circuit connected to the Pic18.Controlling the power through GSM is possible through EUSART modules present in the PIC18. The algorithm is developed using Embedded C. Experimental results show its good performance, when tested with different saliency criteria, such as switching time , less computational time, and the combination of both.
