Abstract
The cascade H-bridge inverters are widely utilized in high voltage and large capacity occasions. Furthermore, it is suitable for the medium voltage level active power filter (APF) field. Considering the high speed response is of great importance for APF application, the large capacity APF generally applies low level switching frequency which will affect the response speed. So it is very important to design appropriate modulation method for large capacity APF. Phase shift PWM (PS-PWM) method can be regarded as a good solution for inverter with low level switching frequency. Further study on PS-PWM is made in this paper and an improved PS-PWM method is presented. With the novel modulation method, high response speed of APF can be guaranteed with relative low switching frequency. The algorism is simple to be implemented. A three-stage cascade APF (CS-APF) simulation model is built and simulated, and the results show that the novel modulation method is an effective and usable solution to promote the response of CS-APF.
