Title: Paul U Lind: Innovator in Power Conversion and Telecommunications
Introduction
Paul U Lind is a notable inventor based in Lombard, IL (US), recognized for his contributions to power conversion and telecommunications technology. He holds 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
One of Lind's latest inventions is the Bi-lateral Four Quadrant Power Converter. This power converter is designed to supply AC or positive or negative DC output voltage with positive or negative current while isolating the output voltage from the input power source. The converter features a pulse width modulator that converts power amplitude signals into pulses of proportionate width. Additionally, a power driver circuit applies these pulses to a synchronous demodulator and low pass filter via a pulse transformer. This design ensures a low output impedance is presented to all output disturbances, allowing the converter to source or sink current in true four quadrant operation, including the ability to transfer power from output to input when a load voltage exceeds the intended supply voltage.
Another significant patent is the Microcomputer Controlled Key Telephone Line Circuit. This invention utilizes a microcomputer to sequentially and alternately scan the ringing leads and tip and ring leads associated with connected line circuits and A leads associated with connected telephone stations. The microcomputer responds to changes in the status of these leads to control essential key telephone functions such as line pickup, hold, ringing current detection, lamp illumination, and tone signaling.
