In domestic induction heating (IH) appliances most commonly the series resonant half-bridge (HB) inverter is used. The number of required components can be further reduced by using non-resonant inverter topologies. Within this contribution, a novel non-resonant multi-output HB inverter for use in flexible cooking surfaces is presented. The proposed inverter topology is described and simulation as well as measurement results are shown. Measurement results are presented for operation with up to two inductors. The hardware prototype is equipped with gallium nitride semiconductors and operates at switching frequencies up to 400 kHz. Measurement results show that an output power of 522 W is reached for use of a single inductor. When using two inductors, a maximum output power of 828 W is reached. The presented results demonstrate the feasibility of the concept, while the efficiency of the system needs to be investigated in future work.

This study aims to elucidate the development and construction of a durable induction cooktop, with key considerations including efficiency, power customization, and safety features. The intricate processes involved in crafting a 3.5 kW induction burner are thoroughly examined, encompassing simulations for quasi-resonant inverters, the meticulous selection of induction coils and capacitors, the implementation of practical Analog-to-Digital Converter (ADC) filtration, pulse width modulation (PWM) driving techniques, and the integration of protection mechanisms. Leveraging an ARM-based microcontroller enabled the attainment of diverse objectives such as Zero-Voltage Switching (ZVS), safeguarding IGBTs, facilitating user interaction through a user-friendly interface, and enabling load detection capabilities. Furthermore, the capability to gauge and adjust output power based on user preferences was incorporated. Subsequently, rigorous testing was conducted to evaluate the functionality and applicability of the device in real-world scenarios.
