对用数字集成电路控制晶闸管的逆变器电路的探讨

A RESEARCH ON THE CONVERTER OF SCR BY U SING DIGITAL INTEGRATED CIRCUIT

本文根据逆变器的ＤＣ—ＡＣ变换的基本原理试图用常用的数字集成电路对六个晶闸管进行控制，并具有可对交流电机进行变频调速，正反转和可靠停转的功能。

Based on the basic alternating principle of AD/AC of converter, this resenrch device applys the digital integrated circuit to control six SCRS. The result of the researchshows that the circuit has the functions of varying frequency regulated speed, reverseturning and reliable stopping.
