摘　　要： 随着绿色能源的发展,pwm整流器技术已成为电力电子技术研究的热点和亮点.由于可以实现电网无污染、功率因数可控以及电能的双向传输,pwm整流器可以作为理想的用电设备或电网与其它电气设备的接口.该论文侧重于三相电压源型pwm整流器及其控制系统的工程设计与实现,以提供一种较为实用的控制器设计与选取方法.论文主要内容包括算法研究、控制器设计、装置开发、样机实验.论文过程中,首先根据三相电压源型pwm整流器各相电压电流之间的关系和桥路的工作状态建立开关仿真模型,并在模型基础上利用matlab软件对电压源型pwm整流器及其控制系统进行仿真设计.其次为实现电压源型pwm整流器双闭环控制系统提供软硬件设计方案.最后采用ti公司的f240芯片作为控制器处理器,三菱公司的ipm模块作为主电路进行小功率样机的实现.论文通过样机实验波形验证了三相电压源型pwm整流器系统仿真设计、工程设计的正确性. With the development of the green power technology, PWM rectifier has become a highlight in the field of power electronics. Due to the merits of pollution-free, adjustable power factor and bi-direction power transfer, the PWM rectifier can be an ideal electric appliance or a linkage between grid-line and other electric facilities. This dissertation focuses on the engineering design and realization of high power three-phase Voltage Source Rectifier /(VSR/) with emphasis on the control technique. The dissertation work, covering the methodology study, controller design, prototype implementation and experiment, is presented as following: Based on the relations between the voltages and currents in accordance with the states of the rectifier topology, the switching function model was first established and then simulated by carefully designed MATLAB programs; The controller's hardware was designed around the TI's F240 processor and corresponding software was also designed to integrate with the hardware to realize a dual-loop VSR control system. Prototype PWM rectifier was build up by choosing IPM as major switching device and experiments delivering results in good conformance with theoretical analysis were performed. The paper concludes with convincing results and expected waveforms that predict the prospect of PWM rectifier.
