Title: The Innovative Mind of William F. MacPherson
Introduction
William F. MacPherson, an accomplished inventor based in Winfield Township, DuPage County, IL, has made significant contributions to the field of electrical engineering through his numerous patents. With a total of nine patents to his name, MacPherson's innovative work has played a crucial role in advancing control circuitry and power conversion technologies.
Latest Patents
Among his latest innovations, MacPherson developed a system for control circuitry using two branch circuits for high voltage solid-state applications. This patent presents a method where a first gated diode switch (GDSL1) can be controlled by applying a voltage that is more positive than either the anode or cathode, simultaneously sourcing current into the gate. This design efficiently controls the state of the switch, incorporating a second gated diode switch (GDSC) to enhance its functionality. Additionally, MacPherson devised a floating battery feed circuit that integrates a switching-mode, flyback power converter. This unique circuit ensures that operations are only enabled when the voltage developed by a connected capacitor surpasses a predetermined threshold, thus maintaining efficient power supply management.
