Title: The Innovative Contributions of Andrew Marsh

Introduction

Andrew Marsh is a notable inventor based in Dallas, TX (US). He has made significant contributions to the field of power electronics, particularly through his innovative patent related to power factor correction methods.

Latest Patents

Marsh holds a patent for an "Interleaved converter power factor correction method and apparatus." This invention discloses an apparatus that equally distributes current from a rectifier circuit to multiple power factor correction circuit units. It achieves this by utilizing equal current magnitudes and reducing component count advantages of peak current sensing, while also minimizing harmonic distortion through average current sensing. The output of a single average current sensing correction circuit in a master controller is logically compared with the output of a peak current sensing circuit in each of the interleaved master and slave controller units. This comparison produces a difference signal that operates the switch in the switch leg of each controller unit, effectively reducing electromagnetic interference (EMI), harmonic distortion, and enhancing the power factor toward an in-phase condition.
