Title: Innovations of Quanqing Wu

Introduction

Quanqing Wu is a notable inventor based in Jiangsu, China. He has made significant contributions to the field of electronics, particularly in the development of circuits and systems that enhance the functionality of LED technology. With a total of 3 patents to his name, his work reflects a commitment to innovation and practical applications.

Latest Patents

Among his latest patents are a PWM signal conversion circuit and method, as well as an LED dimming system. The PWM signal conversion circuit includes a PWM signal 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 by a switch signal generation module to create a switch signal. This process allows for the determination of a duty cycle ratio of the PWM signal, ultimately leading to the generation of an output voltage related to the duty cycle.

The LED dimming system consists of a low-level-voltage generation module, a high-level-voltage generation module, a base-voltage generation module, and a dimming-signal generation module. By counting the high and low levels of a low-frequency PWM signal, the system produces high and low-level voltages over time. A constant current source and capacitor convert high-frequency switching signals into a DC base voltage that is dependent on the duty cycle of the low-frequency PWM signal. This innovative approach allows for effective dimming control of LED lights.
