一种新型的双桥串联顺序控制方法

A New Method with Double Bridges in Sequence Control

提出了一种新型的针对串级调速系统的双桥串联顺序控制方法,通过顺序改变双桥串联控制系统的晶闸管触发角相位,实现了系统功率因数的提高.利用该控制方法,不仅系统的功率因数得到大幅提高,而且系统的谐波也得到有效抑制.为一种实现简单,且行之有效的实用控制方法.

This paper proposed a new control method with double bridges, which improved the power factor by changing the form of the circuit and the phase of the trigger. The method not only improved the power factor, but also suppressed the harmonic in the system. It is an useful and simple method.
