Abstract

The rapid increase in Electric Vehicles (EVs) and the subsequent rise in demand for fast charging infrastructure has emphasized the need for high-performance, efficient rectifiers that adhere to the Power Quality (PQ) standards. This study's primary objective is to design and develop Three-Phase, Two-Level, Unidirectional Rectifiers (3P-2L-URs) for 800V EV chargers. These rectifiers are available in Wye, Delta, and Bridge topologies. To enhance the input PQ and assess the output performance, a control strategy that integrates Voltage-Oriented Control (VOC)-based decoupled controllers with Space Vector Pulse Width Modulation (SVPWM) is proposed. Analytical expressions were used for three-phase modulation signals for each topology and the switching control was designed to minimize the switching losses using a five-segment switching sequence technique. MATLAB/Simulink was deployed to verify the performance of each topology. All topologies met the IEEE 519 and IEC 61000-3 standards, attaining sinusoidal input currents with Total Harmonic Distortion (THD) below 5% and Power Factors (PF) above 99.90%. The Three-Phase, Two-Level, Wye-type, Unidirectional Rectifier (3P-2L-Wye-UR) exhibited the greatest output performance with the lowest voltage and current ripples, making it the most promising solution for high-efficiency EV fast charging applications.
