Speed Control of D. C. Motor Using Teyristor Dual Converter
TLDR
In this article, the authors describe a closed-loop system for the speed control of a separately excited d.c. motor fed from a dual converter, which makes possible regenerative braking and reversal of direction of rotation.Abstract:
The paper describes the design, construction and testing of a closed-loop system for the speed control of a separately excited d.c. motor fed from a dual converter. The dual converter makes possible regenerative braking and reversal of direction of rotation. There is only one firing unit and the firing pulses are diverted to the appropriate converter by a master controller. There are three control loops: one for armature current control, one for adjusting the firing angle of the oncoming converter, and one for speed control.read more
