Title: Innovations of Yuan-Xi Chen
Introduction
Yuan-Xi Chen is a notable inventor based in Shenzhen, China. He has made significant contributions to the field of electrical engineering, particularly in the development of circuits for power management. With a total of 4 patents to his name, his work reflects a commitment to innovation and practical solutions in technology.
Latest Patents
One of his latest patents is a "Circuit for Providing Dummy Load." This circuit includes first to fifth resistors, a comparator, and first to fifth electronic switches. When a power good signal from a power supply is at a low level, the first electronic switch is turned off, while the second to fourth electronic switches are activated. Conversely, when the power good signal is high, the first electronic switch is turned on, and the others are turned off.
Another significant patent is the "Soft-Start Time Control Circuit." This control circuit manages the soft-start time of a DC power supply. It features a digital potentiometer, a first drive circuit, and a controller. The digital potentiometer includes a first potentiometer, while the first drive circuit consists of a first driver, a first MOSFET, and a first charge capacitor. The first driver charges the capacitor when the DC power supply is first activated, and the controller adjusts the resistance of the potentiometer to regulate the charge time constant, allowing for a gradual increase in voltage supplied.
