A Three-Phase Single-Stage ac-dc Converter Based on Swiss Rectifier and Three-Level LLC Topology
Objective
The main objective of this project is to propose a three phase single stage ac-dc converter based on Swiss rectifier and three level LLC topology for grid connected applications.
Abstract
This project presents a three-phase single-stage ac/dc converter based on Swiss rectifier and three-level LLC topology. It takes advantage of the high-efficiency Swiss rectifier to convert three-phase ac voltages into three variable dc voltages and interface a three-level LLC resonant circuit. With help of the LLC resonant tank, all the high-frequency three-level switches achieve soft switching. To both regulate the output voltage and achieve three-phase power factor correction, the frequency modulation in combination with the duty cycle control strategy is employed by splitting the resonant current into three parts and then forming three phase sinusoidal currents. The simulation results can be evaluated by using Matlab/Simulink Software.
Keywords: Full-bridge three-level LLC resonant circuit, soft switching, steady-state characteristic analysis, Swiss rectifier, three-phase single-stage ac/dc converter.
