Title: Drew Kelley and His Patent for a Fault-Tolerant Power Switch.

Introduction

Drew Kelley is an inventor based in Renton, Washington. His patent work includes a design for a solid-state power switch intended to provide fault tolerance while reducing component count, circuit-board space, and heat generation.

Latest Patents

Kelley is associated with 1 patent, titled “Triple Module Redundant Solid State Power Switch.” The patent describes systems and methods for majority-vote switching that can tolerate a single fault in a switch carrying relatively large electrical currents.

The design uses four power transistors and avoids a third electrical branch commonly used in triple-module-redundant power switches. Reducing the number of power transistors can help limit the circuit’s footprint and heat output, particularly when the transistors are large and generate substantial heat.

Career Highlights

Kelley is associated with Blue Origin Manufacturing, LLC. His patented work addresses practical engineering considerations in power-switch design, including fault tolerance, component count, thermal performance, and circuit-board space.
