In order to improve the speed at which electric vehicles (EVs) may be charged using a single-phase distributing grid while reducing electromagnetic interference (EMI), this research presents a revolutionary multi-leg variable frequency converter. The system reduces its need on heavy passive components and increases energy efficiency by employing a multi-leg bridgeless converter. The addition to the high-frequency converter leg allows for enhanced resilience to frequent alterations in the parameters in the proposed architecture. To improve dynamic control in grid-to-vehicle (G2V) along with vehicle-to-grid (V2G) operations, especially in diverging distribution grid scenarios, an adaptive sliding mode control (ASMC) method is used. Even in the face of abrupt changes in adaptive gain, the ASMC guarantees a more responsiveness system by successfully limiting tracking mistakes within predetermined bounds. To improve dynamic control in grid-to-vehicle (G2V) along with vehicle-to-grid (V2G) operations, especially in diverging distribution grid scenarios, an adaptive sliding mode control (ASMC) method is used. Even in the face of abrupt changes in adaptive gain, the ASMC guarantees a more responsiveness system by successfully limiting tracking. Furthermore, by eliminating the requirement to have a fuzzy logic controller, the suggested control technique improves the ability to handle the nonlinearities included in EV charging procedures. The MATLAB program and SIMULINK model is created to examine different spontaneous responses as well as actions in order to assess the system’s performance. To further verify the system’s effectiveness, a hardware laboratory prototype of a 3.3 kW EV charger is built, with a focus on enhancing the source-end power factor under active power exchange in G2V mode.
