Title: Innovations by Yuanyuan Zhao

Introduction

Yuanyuan Zhao is an accomplished inventor based in Reading, MA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of technologies that reduce electromagnetic interference (EMI). With a total of 2 patents, Zhao's work is recognized for its innovative approach to solving complex engineering challenges.

Latest Patents

One of Yuanyuan Zhao's latest patents is the "Micro-scale planar-coil transformer with shield." This invention includes one or more shields that effectively block most common-mode current from crossing from one side to another side of a transformer. The reduction of common-mode current crossing the transformer leads to a decrease in dipole radiation, which is a primary source of EMI in certain transformers.

Another notable patent is the "Power isolator exhibiting low electromagnetic interference." This invention describes power isolators that provide electrical isolation between an input port and an output port while exhibiting low EMI. The low EMI is achieved by canceling out common mode current across a transformer in the power isolator, which may otherwise convert into EMI. The design includes at least one oscillator circuit that applies different signals to two transformers, allowing the common mode currents to partially cancel each other out, thereby reducing the EMI.
