摘要
本文提出了一种用于电压型变频器的新型的PWM方法——均值PWM法,并将它与其它PWM法进行了比较。理论分析与实验研究都证实了新方法的可行性和优越性。
In this paper, a new PWM method-average value PWM is presented. This method has been compared with other PWM methods and realized by using a micro - processor-controlled GTR inverter. Some experimental results and discussions for them have been given.
