Title: Innovations by David W Parsley
Introduction
David W Parsley is an accomplished inventor based in Draper, UT (US). He holds a total of 3 patents that showcase his expertise in power conversion technologies. His innovative designs have contributed significantly to the field of electrical engineering.
Latest Patents
One of his latest patents is the "Switched capacitor interleaved forward power converter." This invention is a DC-to-DC power converter topology that utilizes parallel connected transformers in a buck switching configuration. Each stage operates 180 degrees out-of-phase, with the primary windings of the transformers sequentially feeding into a common filter capacitor. The circuit provides dual inductor buck power stage operation while maintaining input-output isolation. Interleaved power processing ensures continuous capacitance support for the output voltage produced by the power supply.
Another notable patent is the "Dual-inductor buck switching converter." This invention constructs a DC-to-DC power converter by coupling two parallel-connected inductors in series with a DC input power source. A communication switch is connected in series with each of the inductors. The commutation switches are controlled to maintain a switching duty cycle greater than 50%. This design results in an output current to the load that has a greatly reduced ripple and a more constant output current.
