Title: Innovations of James B Thom
Introduction
James B Thom is a notable inventor based in Rock City, IL (US). He has made significant contributions to the field of generator technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and reliability of generator systems.
Latest Patents
One of his latest inventions is the Generator Shorted Diode Protection System. This invention relates to a shorted diode protection system for a brushless alternating current generator that has an energizeable exciter field winding. The system includes a circuit arrangement for sensing the voltage difference across the exciter field and pairing it with generator load current. This provides an output signal that falls within a predictable range of values over a normal generator load current range. The output signal is designed to indicate a higher range of values upon the occurrence of a shorted diode. Another circuit arrangement responds to this output signal, generating an output that interrupts the exciter field when the signal exceeds a preset value.
Another significant patent is the Voltage Regulator. This invention involves a motor-driven generator that incorporates a generator control unit with a programmed microprocessor to manage generator operation. The generator voltage regulator utilizes this microprocessor to develop an error voltage, which is added to the average phase voltage of the generator to control the generator field current. In the event of a phase failure, the generator control unit can sense an abnormally high phase voltage condition and disable the average phase voltage circuit.
