Rectifier Equipment for Electronic D-C Motor Drives

This paper has endeavored to show a functional description of an adjustable voltage rectifier equipment which delivers moderate power and is suitable for the control of one or more d-c motors. These rectifiers incorporate high gain amplifier and excitation circuits which have a high degree of reliability and freedom from frequent maintenance. A well-regulated output voltage is obtained by the use of the Amplistat circuit. The output voltage may be continuously adjusted in response to several system conditions as required. The assembly is made compact and economical by full utilization of the cubicle space. These features make possible a packaged, unit type of rectifier equipment which meets all the service requirements of industrial applications requiring regulated variable voltage source.
