Title: Guocheng Li: Innovator in PWM Signal Conversion and LED Dimming Systems
Introduction
Guocheng Li is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of electrical engineering, particularly in the development of PWM signal conversion circuits and LED dimming systems. With a total of seven patents to his name, Li's work showcases his innovative approach to technology.
Latest Patents
Li's latest patents include a PWM signal conversion circuit and method, as well as an LED dimming system. The PWM signal conversion circuit features a detection module that outputs voltages corresponding to the low and high levels of the PWM signal. An addition module sums these voltages to generate a third voltage, which is then used to create a switch signal. This process allows for the determination of the duty cycle ratio of the PWM signal, ultimately leading to the generation of an output voltage related to the duty cycle. The LED dimming circuit consists of several components, including low and high-level voltage generation modules, which work together to convert high-frequency switching signals into a DC base voltage. This voltage is then used to control the dimming of LEDs based on predetermined conditions.
