Title: Innovations of Keith Pazul in Power Supply Technology
Introduction
Keith Pazul is an accomplished inventor based in Tempe, AZ (US), known for his significant contributions to power supply technology. He holds a total of 3 patents that showcase his expertise in optimizing efficiency in switch-mode power supplies.
Latest Patents
One of his latest patents is a user-configurable, efficiency-optimizing power/energy conversion switch-mode power supply with a serial communications interface. This innovative design features an intelligent pulse width modulation (PWM) controller that adapts the operating parameters of a switch mode power supply (SMPS) system to enhance efficiency, eliminate hot spots, and isolate faults. By integrating a microcontroller, PWM digital circuits, and analog circuits into a single integrated circuit, it reduces the number of external connections and silicon die area. The communications interface allows for monitoring of operating parameters such as current, voltage, efficiency, and diagnostics, while also enabling adjustments to the operating parameters during operation.
Another notable patent is for efficiency-optimizing, calibrated sensorless power/energy conversion in a switch-mode power supply. This invention also utilizes an intelligent PWM controller to optimize efficiency and manage the SMPS system's operating parameters. It incorporates a lossless inductor current sense technique that integrates a matched, tunable complimentary filter with the intelligent SMPS controller. This allows for accurate measurement of current through the power inductor without introducing losses in the power circuit, ensuring precise closed-loop control and overcurrent protection.
