The new generation of wide bandgap power semiconductors such as SiC and GaN are driving the rapid high-frequency,high-efficiency,and small volume development of power electronic equipment. However,they are also more likely to interfere with sensitive loads,affect wireless communication,and even endanger their own safety and reli-able operation,which poses great pressure and challenges to the electromagnetic compatibility(EMC) performance of power electronic equipment. In recent years,the radiated frequency(RF) characteristics of power switches,wideband electromag-netic models of magnetic components,electromagnetic radiation mechanisms of switched mode power supplies,near-field characteristics of wireless power transmission(WPT),and the new designs of electromagnetic interference(EMI) filters have become current research hotspots and received continuous attention from academia and industry. The Journal of Power Supply has specially released the album"Electromagnetic Compatibility in Power Electronic Systems" to promote the ex-ploration of difficult and hot issues in the field of EMC analysis and design of power electronic systems.
