摘要
整流器是产生电力系统谐波的主要原因之一,改变整流器的结构和控制策略,能够有效解决该问题。三相三线制Vienna整流器结构具有功率因数高、开关管电压应力低和输入电流谐波总畸变率低等特点,有较高的应用价值。针对三相三线制Vienna整流器,设计了各部分电路,在Matlab环境下进行了建模与仿真分析,并基于SiC MOSFET搭建了实验平台。实验系统包括主电路、DSP控制、驱动、采样和电源等模块。每个模块具有选择性、独立性和可移植性。该仿真实验平台便于学生深入研究、设计电力电子系统的各个组成部分,提高软、硬件分析设计能力。
Rectifier is one of the main causes of power system harmonics.Changing the structure and control strategy of rectifier can effectively solve this problem.Three-phase three-wire Vienna rectifier topology has the characteristics of high power factor,low voltage stress of switch tube and low total harmonic distortion of input current.It has high application value.In this paper,the three-phase three-wire Vienna rectifier is designed,the model and simulation result are analyzed in MATLAB environment,and the experimental platform is built based on SiC MOSFET.The experimental system includes five modules:the main circuit module,the control module of DSP,the driving module,the sampling module and the power module.Each module has selectivity,independence and portability.The platform is convenient for students to study and design each component of power electronic system in depth,and improve their ability of software and hardware analysis and design.
