Title: The Innovations of Rowland E. Whitford
Introduction
Rowland E. Whitford is a notable inventor based in Painesville, Ohio. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative power supply technologies. With a total of three patents to his name, Whitford's work has had a lasting impact on the industry.
Latest Patents
One of Whitford's latest patents is the Low Level Voltage Pulse-Converter. This device is designed to convert an analog signal into a digital pulse. It utilizes a switching capacitor that is charged by a differential analog signal. The capacitor discharges over an output circuit with the assistance of a constant current supply. The charge level of the capacitor is directly proportional to the analog signal, allowing the time it takes to discharge to a selected low charge level to be used by a microprocessor control to generate a corresponding digital pulse.
Another significant patent is the Low Power High Efficiency Switching Power Supply. This power supply features a switching transducer with primary and secondary windings. The primary winding receives a primary voltage through a series-connected constant current source and Zener diode. The primary voltage is chopped by a field-effect transistor (FET) controlled by a low-frequency oscillator. The secondary windings are connected to full-wave rectifiers that convert the alternating current (A.C.) signal into a direct current (D.C.) signal. This design maximizes efficiency by employing fast switching FETs and low flux densities in the transformer, making it particularly useful in 4-20 mA current loops.
