With the increasing adoption of EVs it is crucial to have a versatile charging system that can support charging of both the wireless EVs and plug-in two wheelers or three wheelers. To meet such a requirement at residential level a three-leg converter configuration is proposed to accommodate charging for both wireless EVs and plug-in vehicles that require DC charging. Such an integration renders economy in device count and eliminates requirement of dedicated charger assembly for each kind of electric vehicle. Both wireless and plug-in EVs can be charged simultaneously with wide range of output voltages in both channels. The wireless charger assembly is based on full bridge for AC level 1 charging for cars while the plug-in charger is based on half bridge LLC topology to contain 2-wheeler and 3-wheeler DC charging requisites. Variable frequency control (VFC) is implemented to achieve the required voltage gains. Using voltage gain analysis and input impedance characteristics, VFC helps to achieve wide voltage output with ZVS realization. The proposed charger topology is simulated using MATLAB Simulink simulation platform to validate the functionality for desired range of output voltage and soft switching provisions.
