| 摘 要： | 为了实现PWM整流器的高效运行,保护良好的动态特性,主电路参数的确定较为关键,但目前现有的选取方法存在一定的盲目性。根据三相电压型PWM整流器主电路结构的数学模型,提出了满足稳态电路指标以及抑制谐波电流的电感值的计算方法,该方法兼顾了交流侧电感跟踪和滤波的两种特性;为满足直流电压跟踪效果以及确保控制系统的电压外环抗扰性能,结合系统瞬态过程的分析提出了直流侧电容选取的方法,从而解决了PWM整流器主电路参数选取的盲目性问题。通过仿真验证了电感值和直流电容参数确定方法的有效性。

| Abstract: | The determination for three phase PWM rectifier main circuit parameters is the key part to implement its efficient operation and keep good dynamic characteristics.But there is a certain blindness about the existing selecting methods.In this paper,a inductor value design method to satisfy steady-state performances and restrain harmonic current and a capacitor selection to meet dc voltage tracking effect and ensure voltage loop anti-interference characteristics are proposed. The mathematical model of the main circuit is based on the three phase voltage source PWM rectifier.The method can solve the blindness of the main circuit parameters selection.The simulation and experimental results are presented to verify the proposed method. |
