In recent years, with the continuous development and wide application of electronic technology, the technology of hand-held electric tools is becoming more and more mature. While pursuing excellent performance, countries have higher and higher requirements for its electromagnetic compatibility, the corresponding standards are also constantly updated and improved, and the threshold of product certification and recognition is higher and higher. It is necessary to study the electromagnetic interference of electric tools and put forward some suppression methods.
