Investigation of matrix converters for AC/DC front-end power supplies

本项目将研究用于高功率高密度前端（AC/DC）电源的矩阵功率转换器的性能。三相-单相矩阵变换器是一种很有前途的拓扑结构，它可以桥接三相电网到任何高频单相输出，而不需要直流链路。该拓扑结构适用于隔离型高压直流配电系统的交流/直流整流器。这些应用包括数据中心的电源、计算机服务器集群、具有直流网络的未来住宅以及许多其他实现直流分布的应用。该项目将评估目前基于矩阵变换器的整流器技术，比较不同整流器的性能，并推荐基于矩阵变换器的整流器设计用于高功率高密度应用。预期研究成果

This project will investigate the performance of matrix power converters for high power high density front end (AC/DC) power supplies. The three phase to single phase matrix converter is a promising topology, which can bridge 3-phase grid to any single phase output with high frequency and without DC link. The topology is suitable for a AC/DC rectifiers for isolated high voltage DC distribution systems. The applications include the power supplies for data center, computer server clusters, future house with DC network, and many other applications where DC distributions are implemented. The project will evaluate the current technology of matrix converter based rectifiers, compare the different rectifiers' performance and recommend the design of matrix converter based rectifier for high power high density applications. It is expected that the research output
