| 摘 要： | 传统的电流型PWM整流器(CSR)一般采用三值逻辑SPWM调制技术,通过相间解耦预处理的方法获得实际PWM控制波形,过程复杂且直流电流利用率较低.本文基于矢量控制思想,充分挖掘DSP芯片二级中断功能,使得三值逻辑PWM控制波形的发生和控制方案的实现大为简化.文中建立了近似的电流型PWM整流器传递函数模型,为系统的综合提供了依据.实验结果验证了电流空间矢量整流器基本原理、PWM波形发生技术以及控制方案的正确性和可行性.

| Abstract: | The three valued logic modulation technique is usually used in the conventional current source PWM rectifier (CSR), and the SPWM control waveform can be obtained by the interphase decoupling.However, the process is complex and the utilization ratio of the direct current is low. Based on the conception of the vector control, the second level interrupt of DSP is fully utilized. Consequently, the generation process of three valued logic PWM and the realization of control scheme are simplified very much. The transform function of the system is also deduced. Experiment results demonstrate the validity and the feasibility of the principle used in current SVPWM, technology of PWM waveform generating and the proposed control scheme. |
