Abstract

This paper surveys recent patents on conducted electromagnetic interference (EMI) reduction techniques for power electronic applications, i.e. switched-mode power supplies and electric drives. Most essential patents currently available are classified into three categories: switching control techniques, modifying topology techniques, and filtering techniques. Significant patented techniques are not only summarized and reported in details, but the usefulness and limitation of benchmarked techniques are also discussed. With this classification and summarization, it would be helpful for power electronic design engineers to be able to appropriately choose EMI reduction techniques with minimum hassle.

Keywords: Electromagnetic compatibility (EMC), electromagnetic interferences (EMI), power electronics, Gate Drive Controls, TOPOLOGY TECHNIQUES, Snubbers, Passive Cancellation Techniques, Hybrid EMI Filters
