Abstract
In recent years, variable speed drives which use stationary inverter supplies have been replacing traditional d-c generator/motor sets. This paper describes a new position sensor consisting of a rotating-light-beam and light-activated-thyristors which may be used to monitor the relative position of the rotor and stator. This information, in turn, is used to control the cyclic firing of the thyristor inverter valves. An experimental model which was successfully tested is described and the analysis and design of the auxiliary turn-off circuit and of the firing-pulse-width control are illustrated.
