Title: Innovations of Qifei Xu in GaN Power Devices

Introduction

Qifei Xu is a notable inventor based in Chengdu, China. He has made significant contributions to the field of power electronics, particularly in the development of GaN (Gallium Nitride) power devices. His innovative work has led to the filing of a patent that showcases his expertise and creativity in this advanced technology.

Latest Patents

Qifei Xu holds a patent for a "Segmented direct gate drive circuit of a depletion mode GaN power device." This invention involves a unique method of charging the gate voltage of a GaN power device. The process begins by charging the gate voltage from a negative voltage turn-off level to the threshold voltage of the device. Once the gate voltage reaches the threshold, a current mirror charging module activates a limited number of charging current mirror modules to elevate the gate voltage to a Miller platform voltage. Subsequently, all charging current mirror modules are engaged to bring the gate voltage to a zero level. This innovative approach enhances the efficiency and performance of GaN power devices.
