开关电源（SMPS）是一个价值数百万美元的产业，在电力电子领域不断发展壮大。开关电源广泛应用于通信、计算机和工业领域。由于最近的立法要求，单位功率因数（UPF）整流器已成为一个重要的设计问题。欧洲立法限制了电源的谐波含量。UPF的优点不仅仅是立法遵从性，这些优点包括更高的效率、更大的功率密度和改善的电能质量，从而为电力服务提供商带来经济效益。

本文的目的是研制一种单位功率因数整流器，研究这种产品的动机是开发一种能够产生低谐波电流畸变率的稳压电源。本课题对非线性负载补偿前后的电流、电压波形以及谐波分量进行了观测。利用MATLAB/SIMULINK电力系统工具箱对该系统进行了仿真，给出了相关仿真结果，并对电源电流进行了改进。

The Switch Mode Power Supplies (SMPS) are amulti-million dollar industry and continuously growing industry within thefield of power electronics. SMPS is widely been used in communication,computers and industrial. The Unity Power Factor (UPF) rectifier has become animportant design issue as a consequence of recent legislation. Europeanlegislation restricts the harmonic content of power supplies. The advantages ofUPF are more than legislative compliance. The advantages include greaterefficiency, larger power density and improved power quality result in economicbenefits to the electricity service provider. The goal of this thesis is todevelop a unity power factor rectifier. The motivation in developing thisproduct was to develop a regulated power supply capable of producing power withlow level of harmonic current distortion. This project observes the current, voltagewaveform and also the harmonics component before and after the compensation tothe nonlinear load. In this work MATLAB/SIMULINK power system toolbox is usedto simulate the proposed system. Simulation results are presented and theimprovement in the supply current will show in this work.
