Title: John E DeFiore: Innovator in AC Induction Motor Control

Introduction

John E DeFiore is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of motor control technologies. His innovative work has led to the creation of a patent that enhances the efficiency and performance of AC induction motors.

Latest Patents

John E DeFiore holds a patent for a Variable Speed AC Induction Motor Controller. This invention involves a circuit designed to power a two-phase AC induction motor. The circuit generates a first signal of the form Vdc+A sin(2.pi.ft-0.degree.) and a second signal of the form Vdc+A sin(2.pi.ft-90.degree.). The first signal is input to a first error amplifier along with a first sampled difference signal from the motor. The second signal is input to a second error amplifier along with a second sampled difference signal from the motor. The outputs from each of the first and second amplifiers are input into a first comparator and a second comparator along with a sawtooth waveform to create a first sinusoidally modulated square wave signal and a second sinusoidally modulated square wave signal. These signals are then fed to driver circuits, which control an H-bridge circuit for powering the motor from a DC bus. This innovative approach allows for improved control and efficiency in motor operations.
