In this paper a simple power and frequency control scheme is proposed for high power/high frequency Induction heating for Typical Heavy Industrial Applications like Induction Welding & Annealing which require operating on 100 kW / 100 kHz. The Proposed PI controller controls the load parameter values of R and L and thereby controls the resonance frequency of the whole model. The control scheme has the advantages of not only wide power regulation range but also ease of control output power. Also, it can achieve the stable and efficient Zero-Voltage-Switching in whole load range. The proposed method is described in detail and its validity is verified through simulink model. The model achieves proper power control for load ranging from 80 kW to 100kw.
