Dual half-bridge inverter with common resonant capacitor is a cost-effective solution that is often used in induction heating appliances. In this topology, a simple and reliable calculation of the power supplied by both inverters would involve measuring the output voltages, both load currents and the resonant-capacitor voltage. This study presents a real-time implementation of two methods to calculate the output powers without measuring the voltage of the resonant capacitor. Simulations are performed to confirm the validity of the methods, which are also experimentally verified through a high-level synthesis implementation in a real prototype with a system-on-chip.
