A transistorized D-C voltage regulator for direct replacement of carbon-pile regulators

FOR SEVERAL years germanium transistors have been available which are capable of controlling appreciable power. The availability of this versatile component has suggested many new product lines. Considering the temperature, current, and voltage ratings of these devices, one application which suggests itself is the use of a power germanium transistor as the static, power-controlling element in a voltage regulator which could replace the traditional carbon-pile regulator presently being used in conjunction with d-c generators in aircraft and ground-power applications.
