A regulator for aircraft D-C generators

IN ORDER to self-excite and regulate a d-c generator, a device is needed which can vary the current supplied to the shunt field of the machine so that regulated voltage results over a wide range of speed and load. In addition, it must provide some means of load sharing when one generator and its regulator are paralleled with one or more identical systems. In 71 C ambient, this can be accomplished by a carbon-pile regulator or by a switching-type regulator using germanium transistors.
