Abstract: This article entrusts a hybrid asymmetric voltage cancellation (AVC) and pulse density modulation (PDM) switching scheme for full bridge resonant converter which can be applied for induction heating (IH) application. The single stage converter topology suggested in this paper is efficient compared to the conventional dual stage. The pulse generation for the converter is strategically performed by hybridizing AVC and PDM techniques. The inherent dead band in AVC technique facilities soft switching, in turn, reduces the switching losses, whereas PDM enhances the power control ranges without a change in switching frequency. IH application requires a wide range of power control with minimal losses. This research put forth an effort to hybridize AVC and PDM to enhance the control and conversion without a change in frequency. The work has been duly simulated in a simulation environment (MATLAB/Simulink) and also a hardware prototype has been realized. The results prove that the work is advantageous in many aspects.
