摘要
三相电压型PWM整流器因其具有输入电流正弦性好，可获得单位功率因数，输出电压跟踪性好，可有效滤除系统谐波等特性，成为目前电力电子领域中被广泛研究的课题之一。
PWM整流器按其拓扑结构可分为电压型PWM整流器和电流型PWM整流器，本文对电压型PWM整流器的拓扑结构和工作原理进行了较为详细的分析，提出了用空间电压矢量方法分析三相单位功率因数电压型PWM整流器的换流方式。
在电网中，PWM整流器可与其他非线性负载并联运行，而这些非线性负载产生谐波电流对电网造成巨大污染，这就要求PWM整流器在输出稳定的直流电压的同时还应实现有源滤波的功能。PWM整流器与有源滤波器具有基本相同的电路结构，因此可以通过一种控制方法将PWM整流器的两项功能统一起来。本文采用重复学习Boost变换技术，利用滑模变结构控制技术对单相PWM整流器恒频Boost变换进行了分析，提出将交流侧电流直接与三角波(或锯齿波)相比较得到开关控制信号的方法，实现直流电压恒定不变及系统单位功率因数；同时，利用瞬时无功功率法分析系统谐波，并在谐波域内使用重复学习的控制方法，结合Boost变换技术，有效滤除系统谐波有功电流。本文在确定系统参数的基础上对基于重复学习Boost变换控制的三相PWM整流器进行了仿真研究，结果证实了这种方法的正确性和可靠性。
本文将基于重复学习Boost变换控制的三相PWM整流器应用于高压变频器系统中，仿真实验结果表明高压变频器的输入电流基本接近正弦波，输出电压理想，为高压变频器的改进提供了理论依据。
The three-phase voltage source PWM rectifier is becoming interested in power electronics field because it has many excellent characteristics such as undistorted sinusoidal current waveform, unity power factor,
According to the topology, PWM rectifier is divided into voltage source rectifier (VSR) and current source rectifier (CSR). The topology and principle of voltage source rectifier are analyzed in detail and the space voltage vector method is explored to investigate the inversion of the three-phase voltage source PWM rectifier in this paper.
A new control method Integrated Learning Boost Converter Control is presented in the paper to implement the two functions of PWM rectifier: commutating and filter. The Boost converter is analyzed through the theory of Sliding Model Variable Structure in this paper. The control signals of the PWM rectifier are obtained by comparing the current of AC side with triangular wave (or saw-tooth wave) directly, which can implement the steadiness of the voltage of DC side and unit capacity factor of the system. At the same time, harmonic component of the system is abstracted through Instant Reactive Power Method, which can be smoothed by Integrated Learning Boost Converter Control. After calculating the system parameter, such as the inductance of AC side and the capacitance of DC side, we accomplished the simulation of the three-phase voltage source PWM rectifier, and the result proves correctness and reliability of the control method.
Three-phase voltage source PWM rectifier based on Integrated Learning Boost Converter Control is applied in high-voltage frequency-converter system, and the result of simulation and experiment is ideal?
