Title: Yunpeng Li: Inventor of an Analog Quantity Acquisition Method
Introduction
Yunpeng Li is an inventor based in Beijing, China. His patent work includes a method and apparatus for accurately acquiring analog current signals.
Latest Patents
Li is associated with 1 patent, titled “Analog Quantity Acquisition Method and Apparatus.” The invention uses a zero-flux current transformer, a compensating winding, and a dynamic detection unit to acquire a current signal. The compensating winding generates a reverse excitation potential to counteract excitation current, helping reduce the effects of ratio and phase-angle errors on measurement accuracy. A multi-segment amplification circuit amplifies different current ranges, and an analog-to-digital converter converts the amplified signal into digital form.
Career Highlights
Li has been associated with State Grid Info-Telecom Great Power Science and Technology Co., Ltd. and Fujian Netpower Technology Development Co., Ltd. His patent focuses on improving the accuracy and range of current acquisition.
Collaborations
Li’s listed coworkers include Chuanjian Cui and Yonggui Wang.
Conclusion
Yunpeng Li’s patent combines zero-flux current sensing, segmented amplification, and digital conversion to support accurate measurement across different current ranges.
