Analysis And Control Of Resonant Converter For Induction Heating Systems

Abstract

Acceptance warming innovation is a high recurrence warming newlinestrategy in the field of cooking. The essential guideline behind the newlineinnovation is faradays law of electromagnetic induction. The centre of newlineattention towards the Induction heating technology is safety, cleanliness, newlineuniform distribution of heat, reliable and compactness. The power newlineconverter circuit employed with AC-DC-AC or AC-AC which produces newlinehigh frequency output. Single stage AC-AC series resonant converter is newlinesimulated with full bridge and half bridge topology. First and foremost newlinethe simulation of the Single stage half bridge AC-AC series resonant newlineconverter topology with pulse density modulation was carried out using newlineMATLAB Simulink. Secondly the full bridge topology is simulated and newlinethe results are interpreted .A new 28 kHz, 610W Single stage half bridge newlineAC-AC series resonant converter for IH technology is suggested for newlineimplementation. newlineThe coil resistance variation was simulated and outcomes got newlineare organized and looked at. With the outcomes got in the reproduction newlinea model for the acceptance cooking framework was created and the newlinevarieties in the temperature concerning time are arranged for approval. newlineFurther to visualize the electromagnetic parameters of the coil a virtual newlineinduction cooking model was designed. Magnetic flux density of the newlinecoil, current density, intensity, solid loss, and winding loss is the newlineparameters visualized for induction coil. The cook top material, newlinethickness size and the quantity of the material affects the coil newlineperformance. To analyze the performance of the induction coil FEA was newlinecarried out using simulation platform EMWorks. Number of iterations newlinevi newlinewas carried out to get the satisfactory results. Various results are newlinepresented in the thesis to observe the changes in IH coil. newlineHere a 28 kHz, 15A, 610W high frequency single stage half newlinebridge AC-AC series resonant converter with the specified coil newlineparameters is developed and its performances are validated with the newlinenumber of iteration in the developed virtual model. Thus the ef
