This research describes a three-phase rectifier that can process three different DC voltages (low, medium, and high) at once. In this research, we assess and analyze a modified double-loop decoupling SVPWM approach based on asymmetric two-level vector space for transferring energy directly from the AC port to the low voltage DC port inside single-stage power conversion. The low voltage port with the broad voltage range may get power straight from the AC grid thanks to the rectifier and the improved SVPWM management technique. As a result, we may use a lower-rated downstream DC-DC converter and fewer stages of power conversion. Compared to the conventional two-stage rectifier, which consists of a three-phase two-level rectifier wired to the vehicle's energy storage system, the given architecture and vector space are distinctive. Matlab-Simulink was used to model the system and show that lower harmonics lead to greater performance.
