Title: Ralph R Boudreaux, Jr: Innovator in Telecommunications
Introduction
Ralph R Boudreaux, Jr. is a notable inventor based in Madison, AL (US), recognized for his contributions to the field of telecommunications. With a total of 12 patents to his name, Boudreaux has made significant advancements in power conversion technologies that enhance telephony systems.
Latest Patents
One of his latest patents is the "Tracking switchmode power converter for telephony interface circuit." This invention involves a comparator-based switchmode power converter that monitors the most negative of the tip and ring line voltages. It controls the supply voltage to a Subscriber Line Interface Circuit (SLIC), ensuring that the voltage applied to the SLIC's power terminals is slightly higher than the sensed voltage under various loop signaling conditions. The switchmode converter includes a comparator coupled to a DC-DC output node downstream of a MOSFET switch, which is installed in a DC supply rail. This setup allows for power supply tracking during loop current, superimposed voice signals, loop start, ground start, and balanced ringing.
Another significant patent is the "Method and apparatus for limiting ground fault current." This invention features a ground fault current-limiting circuit designed to maintain telecommunication wireline voltage and ground fault current within prescribed safety parameters. It utilizes a ground fault current sense resistor and an associated line voltage control circuit to compare the ground fault current to a prescribed value. When the current limit is exceeded, the control circuit produces an output signal that prompts the power source to reduce its output voltage, ensuring safety and compliance.
