Introduction

Peng Xu is an accomplished inventor based in Sleepy Hollow, NY (US). He has made significant contributions to the field of voltage regulation through his innovative designs and patents. His work focuses on improving the efficiency and performance of voltage regulator modules (VRMs).

Latest Patents

Peng Xu holds a patent for a "Multiphase clamp coupled-buck converter and magnetic integration." This invention enhances the voltage regulation, transient response, and efficiency of VRMs, particularly when short duty cycles are required due to large differentials between input and output voltage. The design incorporates at least one clamping of a tap of an inductance in series with the output of each of a plurality of parallel branches or phases, which are switched in a complementary manner. The coupling between inductors of respective phases is achieved within a compact module featuring an integrated magnetic structure. This innovation reduces component counts while providing built-in input and output filters. The principles of this invention can also be extended to isolation applications and push-pull forward converters. Additionally, a lossless clamping circuit is included, which suppresses spike currents while returning power to the output of the VRM.
