摘要
本文讨论了利用ML4423芯片实现PWM的变频控制,给出了ML4423在系统中的应用,最后给出了运行实验结果。该控制系统价格低廉,性能良好,是一种值得推广的低成本、小体积单相变频器设计方法。
This paper discusses that realizes PWM adjustable - speed drive with ML4423 chip for single - phase alternator. The system for application of ML4423 is given out. At last the practical result is presented. This control system is low in price and the performance is good, which is one kind of worth promoting design method with low cost and small volume single -phase frequency changer.
