摘要
提出了级联型相移 SPWM变流器的概念 ,该变流器能在较低的器件开关频率下实现较高开关频率的效果 ,具有结构简单、传输频带宽、动态响应好等优点。通过仿真证明该技术在电力有源滤波器这样的大功率场合具有广泛的应用前景。
The concept of a cascade converter based on the phase-shifted SPWM technique is proposed. It can have high efficient frequency even for devices with low switching frequency and also has such advantages as brief structure, wide bandwidth and good dynamic response in large power equipment. The active power filter with this technique has been simulated, whose results are promising. This project is supported by National Natural Science Foundation of China (No. 59777023).
