Title: William J. Laughton: Power Synchronization and Switching Circuit Inventions

Introduction

William J. Laughton is an inventor associated with Syracuse, New York. His work includes inventions in power-converter synchronization and switching circuitry. He is credited with 8 patents.

Latest Patents

One of Laughton’s latest patents, “Automatic Equal-Phase Synchronizer for a Varying Number of Synchronized” describes a system for coordinating multiple power converters aboard a spacecraft. The invention generates synchronization pulses at equal phase intervals for the converters. If a converter fails, the system adjusts the timing intervals so the remaining converters can continue operating in synchronization.

Another patent, “Symmetrical Delay Circuit,” concerns dead-time circuitry for bridge switching devices. The circuit independently delays the rising and falling edges of signal pulses to help prevent two switching devices in the same bridge leg from conducting simultaneously.

Career Highlights

Laughton’s career includes work associated with General Electric Company and Martin Marietta Corporation. His patented inventions address practical challenges in power electronics, including reliable synchronization and safe switching.

Collaborations

Among Laughton’s coworkers were Glenn Scott Claydon and William P. Kornrumpf.

Conclusion

William J. Laughton’s patents reflect a focus on dependable power-conversion systems, with inventions designed to maintain synchronization and prevent unsafe simultaneous switching.
