Induction heating (IH) technique has been widely used in industrial and domestic heating applications. In IH cooking applications, multi‐output IH systems are increasing in demand. In this study, an inverter configuration is proposed for two‐output IH cooking applications. The objective of this proposal is to reduce the component count and thereby the size of the circuit and cost. In this proposed configuration, two IH loads are connected to a full‐bridge inverter output and these loads are sharing a common resonant capacitor. The output power is controlled using on–off control. Switching losses are reduced due to zero voltage switching operation. The two loads are independently controlled with high efficiency. The control logic of the proposed system is described in detail and prototype is designed, implemented and the validity is verified through experimental and simulation results.
