A BIDIRECTIONAL SWITCH BASED HIGH-EFFICIENCY ISOLATED RESONANT CONVERTER FOR PLUG-IN HYBRID ELECTRIC VEHICLE CHARGING

Abstract: This paper presents a high efficiency resonant converter over a wide output voltage range with PV module for PHEV application. This method brings voltage regulation by using technique of fixed frequency pulse width modulation(PWM) control, by adding bidirectional switch on secondary side of resonant converter and direct power transfer to load is also achieved ref [1][2]. Simulation results are given to confirm the proposed method achieves wide range of voltage. Thus the proposed method provides high efficiency and it is more suited for battery charging application, PLUG-IN hybrid electric vehicle (PHEV) ref[6].Experimental results shows that the proposed method of hybrid series resonant and PWM boost converter can achieve the peak efficiency of over wide range
