Title: John E. Shepler: Innovator in Generating Systems
Introduction
John E. Shepler is a notable inventor based in Rockford, IL (US), recognized for his contributions to generating systems. With a total of 4 patents, Shepler has made significant advancements in the field of electrical engineering.
Latest Patents
One of his latest patents is a generating system with fault detection. This innovation prevents 'doorbelling' in a generating system that includes a fault detecting circuit without the need for an auxiliary power supply for a generator control unit. The system features a permanent magnet generator driving an exciter winding, with a relay utilized for interconnecting the two. Control of the relay is managed by a microcomputer programmed to remember fault occurrences, thereby preventing unnecessary cycling of the relay in response to power changes.
Another significant patent is a frequency detector system. This system includes a processor and a counter that derives a digital count proportional to the output frequency of the generating system. The processor executes control cycles to manage the speed of the generating system based on the output frequency. The design minimizes complexity by eliminating the need for an interrupt handling procedure.
