Abstract
Static converters are used in many different areas of the conversion of electrical energy. Significant developments in electric power switches and variety of design techniques of control and regulation circuits bring very advantageous solutions for congestion, reliability, performance and maintenance of converters. The present work focuses on the study and implementation of an Arc cosine pulse generator for commutated converter acting on a composite bridge in order to linearly control the speed of a DC motor. The principle of the control of the Arc cosine pulse generator for commutated converter is based on the fact the average rectified voltage is proportional to the control voltage as the rectified voltage is a function of the average cos?, which over a wide beach, is clearly non-linear. But for tension adjustment needs over a wide range, with a control voltage and constant ratio, it is often necessary to linearize the control. This allows a similarly linear variation in the speed of the DC motor.
