| Summary |
"The methods of obtaining voltage regulation for a d-c generator are many, and they vary in complexity according to the requirements of the loads being supplied. A need for zero voltage regulation is not uncommon in power supplies that are used in laboratory work. It is frequently not enough, however, to have a supply whose steady state regulation is zero; the need may also exist for fast transient response to changes in load. In general, then, the criteria for excellent voltage-versus-load characteristics of a d-c power supply might be stated as follows: 1. It has zero steady state error. 2. It has no transient variations as load is varied in any manner. Of course a power supply which exhibits such excellence of voltage regulation is non-existant [sic], but these criteria do establish a goal for the regulator designer. There are many approaches to the solution of the voltage regulation problem, but in general all regulators can be classified as closed-loop or open-loop systems. It is with the former type of system that this paper is concerned. More specifically this paper will present mathematical and experimental design studies of two closed-loop voltage regulators for use with a 125V 4 Kw d-c generator"--Introduction, leaf 1. |
