Latest Patents
Feng Shi's latest patents include innovative designs that enhance the efficiency of electrical systems. One of his patents is titled "Current control systems with current feedbacks." This invention features a current control system that includes a first switch, a second switch, and a controller. The second switch operates in parallel with the first switch and provides a feedback signal indicative of the current flowing through the first switch. The feedback signal is determined by the width-to-length ratios of both switches. The controller adjusts the current based on this feedback signal.
Another significant patent is "Circuits and methods for controlling a light source." This invention comprises a driving circuit that controls a light source using a frequency controller and a switch module. The frequency controller receives a first dimming signal to achieve a predetermined brightness. It generates a second dimming signal with a frequency outside predetermined ranges when the first dimming signal is within those ranges. The switch module alternates on and off to maintain the desired brightness based on the second dimming signal.
