Title: The Innovations of Joseph R Pottebaum
Introduction
Joseph R Pottebaum is a notable inventor based in Brookfield, WI (US), recognized for his contributions to motor control technology. With a total of five patents to his name, Pottebaum has made significant advancements in the field of variable frequency motor drives and AC power line current regeneration.
Latest Patents
One of his latest patents is titled "Motor speed control with speed foldback for phase imbalance protection." This invention involves a variable frequency motor drive that includes a converter with a rectifier, which converts AC power to DC power. The system features a DC bus connected to the rectifier circuit, with at least one bus capacitor across the DC bus. An inverter receives the DC power and converts it back to AC power to drive a motor. The controller connected to the converter regulates the inverter's operation to maintain the desired motor speed, utilizing a speed foldback control that measures DC bus ripple voltage.
Another significant patent is the "AC power line current regeneration." This method and circuitry energize an AC power line from a DC power source through pulse width modulated switch means. The process involves sampling the required peak line regeneration current value from a previous PWM cycle and calculating the necessary peak line regeneration current for the present cycle based on previous measurements.
