Thyristor electric actuator with a wide range of speed control.

Abstract

The results of theoretical and experimental studies of a nonreverse thyristor electric drive consisting of a phase control system, a three-phase thyristor converter and a DC motor are presented. The phase control system is executed on the basis of the phase separator RС. The phase control system and the thyristor converter have a linear transmitting characteristic and a high multiplication factor. For obtaining qualitative transient processes during start-up in the circuit applied, approves current limit, and quality of transient modes is provided by applying sequential correction on passive elements.
