The global fast charging market is projected to grow at a CAGR of 22.1% from 2023 to 2030 (Grand View Research, 2023), driven by rising demand for electric vehicles and portable electronics. Koyaya, tsangwama na lantarki (EMI) ya kasance ƙalubalance mai mahimmanci, tare da raunin cajin aiki a cikin na'urorin Cliperarfin PRIPS (IEEEL ma'amala kan abubuwan lantarki, 2022). Wannan labarin ya bayyana hanyoyin da za'a iya aiwatarwa don magance EMI yayin da kiyaye ingancin caji.
