论文部分内容阅读
现在,变频器的应用已经相当地普及了,本刊也发表了不少介绍变频器应用方面的文章。但有的读者反映:迄今为止,几乎见不到介绍应用变频器的基本控制电路的文章。为此,本刊特邀请张燕宾同志撰写《变频调速应用电路》的连载文章,主要内容有:变频调速系统的主电路、正转控制电路、正反转控制电路、与工频切换的控制电路、多档速控制电路、多处控制电路、同步控制电路、轮流运行控制电路等。读者在这方面还有什么要求,可以继续向本刊反映,也可以直接和张老师联系。
Now, the application of the inverter has been quite popular, the publication also published a lot of articles on the application of the inverter. However, some readers said: So far, almost no application introduction of the basic control circuit of the inverter article. To this end, this article invited Comrade Zhang Yanbin invited to write a “variable frequency speed control circuit,” a series of articles, the main contents are: frequency control system of the main circuit, forward control circuit, positive and negative control circuit, and the switching frequency control Circuit, multi-speed control circuit, multiple control circuits, synchronous control circuit, running control circuit and so on. Readers in this area what are the requirements, you can continue to reflect this article, you can also contact Zhang and teachers.
