Title: **Joseph C. Buxton: Innovator in Power Regulation Technology**
Introduction
Joseph C. Buxton, an accomplished inventor based in Palo Alto, California, holds an impressive portfolio of 7 patents. His work primarily focuses on advancements in power regulation technologies, contributing significantly to the fields of electrical engineering and circuit design.
Latest Patents
Among his latest inventions is a patent relating to "Controlling a bidirectional DC-to-DC converter." This innovative approach regulates power flow and limits inductor current in bidirectional DC-to-DC converters. The invention employs a feedback circuit to manage power flow based on input/output voltage and current conditions. In boost mode, it decreases the low-side switch's duty cycle through analysis of high-side voltage and positive inductor current. Conversely, in buck mode, it elevates the duty cycle based on low-side voltage and negative inductor current. This system ensures that the converter's operational parameters remain within preset thresholds, returning to a steady state efficiently.
Another notable patent is for a "Multi-phase switching regulator." This invention features an N-phase switching voltage regulator that includes N current sensing elements. These elements detect respective phase currents and present their voltages to an amplifier, creating an output proportional to the total current. The design features active voltage positioning (AVP) by incorporating total inductor output current information into the voltage-mode control loop. This advancement enhances the regulator’s ability to maintain desired droop impedance characteristics, thereby improving overall performance.
