Induction electric heating utilizes the momentum of skin effect resulting from eddy current. In this study, the eddy currents exist in coils that have been induced from the heating and skin effect occurs on the skin of coil sheath that induces heat on the workpiece. This study also discussed the design of one induction electric heating method that is rarely used in cooker’s coils that using resonant circuit of zero-voltage switching (ZVS). Typically, ZVS circuits are used on heater coils such as solenoid-shaped coils, so, in this study, there is an opportunity to utilize ZVS resonant circuit for heating on cooker coils in the form of pancake coils. The ZVS assisted the induction process in the heating control circuit. It used an Arduino Uno-based control circuit due to complete parts and compact. The microcontroller was played as the keypad and pushbutton input control. The sensor and display were played as the output. From the test results to determine the size of toroid transformers obtained toroid black type with a cable size about 1.5 mm solid with 10 turns. To determine the size of the coil pancake obtained air gap copper wire with a diameter of 4.7 mm (≈5 mm) with 12 turns. The average temperature rise reached 0.0815°C/s and 0.0889°C/s for the thermocouple and thermometer readings, respectively. The average heating rates were 21.4 cal/s and 81.6 cal/s, respectively for collector 1 and collector 2. The higher the temperature want to achieve, the lower the value of heat transfer efficiency. The yielded induction heating operational frequency on both channel was almost balanced at a frequency of 130-131 kHz, before shunt resistor installation. This small variation was probably cause by the choke position which was influenced by the pancake coil that was not exactly in the middle of the overall length of the coil. While, after shunt resistor installation, the yielded induction heating operational frequency was 125 kHz, which was for measurement purposes. Keywords: heating rate, pancake coil, temperature rise, workpiece, zero-voltage switching (ZVS)
