Abstract (englisch):

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.
