The paper surveys the development of aircraft voltage and frequency regulators from early days to the present, as aircraft generating equipment progressed from third-brush d.c. machines to constant-frequency alternators. The development of generator driving systems is reviewed, and some early d.c. voltage regulators are described. The carbon-pile regulator is discussed in some detail, and various types of voltage and frequency regulators for d.c./a.c. inverters are described and criticized. Some account is given of regulating equipment for both variable-frequency and constant-frequency a.c. systems. The underlying problems of regulator design are outlined, with an indication of possible future developments.
