三相电压型PWM整流器的设计与实现

PWM控制技术一直是变频技术的核心技术之一。从最初采用模拟电路完成三角调制波和参考正弦波比较，产生正弦脉宽调制SPWM信号以控制功率器件的开关开始，到目前采用全数字化方案，完成优化的实时在线的PWM信号输出，可以说直到目前为止，PWM在各种应用场合仍占主导地位,并一直是人们研究的热点。SIMULINK是结合了框图界面和交互仿真能力的非线性动态系统仿真工具。它以MATLAB的核心数学、图形和语言为基础。利用SIMULINK实现对PWM波形的仿真可以得到PWM的标准波形,对于PWM波形的分析及老师教学都有重要用途。 [来源：http://www.think58.com]

The PWM control technology has been one of frequency conversion technology core technologies. From uses the analogous circuit to complete the triangle modulating wave and the reference sine wave comparison at first, produces the sine pulse-duration modulation SPWM signal to control the power component's switch start, uses the entire digitized plan to at present, completes optimized the real-time online PWM signal output, may say until present, PWM still occupied the dominant position in each kind of application situation, and has been the hot spot which the people study. SIMULINK unified the diagram contact surface and the interactive simulation ability misalignment dynamic system simulation tool. It take the MATLAB core mathematics, the graph and the language as the foundation. Realizes using SIMULINK to the PWM profile simulation may obtain the PWM standard wave pattern, the profile analysis and teacher the teaching has the important use regarding PWM.
