Abstract
The project titled Enhanced Soft Switching Operation of Three-Level Buck Converter Using ZVS Method for EV chargers is by minimizing switching losses in buck converter. Conventional two-level converters suffer from higher voltage stress and switching losses, especially at high switching frequencies. To overcome these issues, a three-level buck converter topology is implemented using the Zero Voltage Switching (ZVS) technique. By achieving soft switching conditions, the power MOSFETs are turned on and off at near-zero voltage, effectively reducing switching losses and electromagnetic interference (EMI). The proposed converter operates in Continuous Conduction Mode (CCM) with improved voltage regulation and reduced thermal stress on switches. Simulation and hardware implementation results validate the performance improvement in terms of efficiency, voltage stress reduction, and smooth transient response. This technique finds practical applications in Electric Vehicle (EV) battery charging systems and other high-efficiency DC power applications
