Design and Construction of Variable Direct Current Speed Drive

H.M. Talukder, A.V. Gholap, P. Rugube

Abstract


A direct current variable speed drive is designed and constructed using silicon-controlled rectifiers from the viewpoint of simplicity and cost effectiveness to act as power converter and controller. Design and construction of constituent circuits such as acceleration/deceleration, speed and current amplifier and the trigger circuit are presented together with their corresponding input and output waveforms.
