Title: The Innovations of Frederick J Kuehn, Jr.
Introduction
Frederick J Kuehn, Jr. is a notable inventor based in Erie, PA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of control systems for generators. His innovative work has led to the creation of a patent that enhances the functionality of self-excited alternators.
Latest Patents
Kuehn holds a patent for a "Control system for a tertiary winding self-excited generator." This invention involves a control system designed for a self-excited alternator, which includes an auxiliary winding that supplies excitation to the alternator field winding. The system incorporates a circuit that supplements field excitation when the energy from the auxiliary winding is insufficient. The self-exciting alternating current from the auxiliary winding is coupled through a phase-controlled rectifier circuit to the alternator field winding. Additionally, a secondary excitation source, such as a battery, is connected to the alternator field winding through a chopper circuit. A regulating circuit responds to a field current reference signal to control the conduction of both the phase-controlled rectifier circuit and the chopper circuit, ensuring that the alternator field excitation is maintained at the desired level.
