A controlled rectifier regulator for aircraft D-C generators in 120 C applications
A. L. Wellford · Transactions of the American Institute of Electrical Engineers Part II Applications and Industry · 1960
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 (degrees centigrade) ambient this can be accomplished by a carbon-pile regulator or by a switching type of regulator using germanium transistors.1
