Title: **The Innovations of Ronald B. Hulfachor: A Pioneer in Power Conversion Technology**
Introduction
Ronald B. Hulfachor, based in Cape Elizabeth, ME, is a distinguished inventor with an impressive portfolio of 18 patents. His contributions primarily focus on advancements in switched-mode power conversion technologies, showcasing his significant impact on the field of electrical engineering.
Latest Patents
Ronald's latest innovations include two notable patents centered around isolated switched-mode power converters. The first patent addresses an isolated switched-mode power converter that efficiently converts power from an input source into power for an output load. This invention features a digital controller that senses a secondary-side voltage, such as a rectified voltage. It employs a high-impedance voltage divider to divide down the secondary-side voltage, which is then processed by a voltage sensor within the digital controller. This sensor level shifts and buffers the voltage, ultimately providing it to a tracking analog-to-digital converter (ADC) for digitization. This unique design ensures that the buffered signal has a high current capability, allowing the tracking ADC to quickly converge before outputting a digital value for the sensed voltage.
The second patent expounds further on the processes involved in secondary-side rectified voltage sensing, reiterating the importance of a high-impedance voltage divider and the role of the digital controller in enhancing the performance of isolated switched-mode power converters. Both patents reflect Hulfachor's commitment to innovation in energy conversion and efficiency.
