Title: The Innovations of Eugene Francis Plutowski

Introduction

Eugene Francis Plutowski is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of motor control systems, holding a total of 8 patents. His work focuses on enhancing the performance and reliability of motor controllers, particularly in applications involving pulse-width modulation.

Latest Patents

Among his latest patents is the invention titled "Rejection of power supply variations for gain error cancellation in pulse-width-modulated motor controllers." This invention discloses a positioning driver for a voice coil motor in a disk drive system. The system utilizes pulse-width-modulated prestage drivers coupled to power transistors arranged in an 'H' bridge configuration. These drivers operate based on a comparison between an error signal from an error amplifier and a ramp clock signal generated by a ramp clock generator. The ramp clock generator includes a control circuit that modulates the high and low limits of the ramp clock signal in response to variations in the power supply voltage, thereby compensating for variations in the gain of the power transistors.

Another significant patent is the "Closed-loop control system to mitigate PWM switching noise." This invention provides a motor control system that operates in both linear and pulse-width modulation modes. It generates control signals for driving the motor based on an error signal, with a feedback network that matches the responses in both modes, facilitating smooth transitions.
