A Modified Zeta Converter fed with HB-LLC Resonant Converter for Power Factor Correction

This paper presents the Modified Zeta Converter fed with HB- LLC Resonant converter for Electric Vehicle applications. The Modified Zeta Converter operates in Discontinuous Conduction mode (DCM) and LLC Resonant Converter is used to transfer the DC-Link power to the battery. Collective combination of these two converters for the EV charger results in smooth operation, reduced voltage stress across the PFC devices and Modified efficiency of the converters. This work mainly focuses on designing the components of the converter and comparison of the Modified and Conventional Zeta Converter fed HB-LLC Resonant Converter in MATLAB/Simulink environment.
