Abstract
- This paper presents a double half bridge resonant inverter for induction heating (IH) system composed of two partly coupled coils. Induction coils are electrically characterized by their electrical equivalents, usually a series RL circuit, where the inductance is determined by the magnetic energy stored in the system and the resistance is associated with the power dissipated in the load. Pulse width modulation based control strategy for double half bridge resonant inverter based power supply circuit is presented. The aim of this work is to simulate and obtain the electrical equivalent of the inductor system for accurate power study with two concentric coils by considering the frequency dependent eddy current losses associated with both the pan and the coil. This paper gives an idea about the in new control modes taking advantage of the coupling between coils in order to provide the target output power. The performed analysis includes the description of the operation and principle of the control strategy. The power converter system is designed and the simulation results are presented to prove the performance of the double half bridge inverter for partly coupled induction heating coil.
