Title: Yucai Yang and Isolated Power Supply Control

Introduction

Yucai Yang is an inventor based in Shanghai, China. His patent work concerns control methods for isolated power supplies, including coordination between a primary transistor switch and a secondary synchronous rectifier.

Latest Patents

Yang is associated with 1 patent: “Isolated Power Supply, Control Circuit and Method Thereof.” The invention describes a control circuit that generates a primary turn-on signal based on feedback from the power supply’s output voltage. It also generates a secondary control signal using a secondary voltage signal and the primary signal. During a switching period, the secondary signal indicates that the synchronous rectifier should turn on only when the expected turn-on instant of the primary main transistor switch comes earlier than that of the secondary synchronous rectifier.

Career Highlights
