Title: David King Wai Li: Innovator in Power Conversion Technology
Introduction
David King Wai Li is a notable inventor based in Toronto, Canada. He has made significant contributions to the field of power conversion technology, holding 2 patents that showcase his innovative approach to electrical engineering.
Latest Patents
One of his latest patents is a DC-DC converter controller. This predictive controller is designed for an inductive DC-DC converter that includes a switchable inductor. The controller generates multiple switching phases to manage the inductor current, with the duration of these phases determined by reference values for inductor current and output voltage. Additionally, the predictive controller features a supervisory controller that adjusts the reference inductor current based on expected changes in load current or voltage, utilizing a predetermined load profile.
Another significant patent is for a multiple output charge pump with peak voltage following frequency divider control. This power converter dynamically adjusts its supply voltage to meet the varying power requirements of a load. It tracks the radio frequency (RF) envelope of the signal carried by the load, providing multiple output voltage levels through a charge pump. A controller modifies the selected voltage level to ensure it aligns with the RF envelope, while a peak following frequency divider circuit limits the switching frequency to optimize performance.
