Switching converters require effective EMI filters to comply with conducted emission regulations. However, these filters often pose significant challenges, being expensive, bulky and heavy. The situation is further exacerbated with the latest generation of converters, utilizing WBG semiconductor devices, which operate at higher switching frequencies. Reduction of the filter size can be achieved through conducted EMI mitigation techniques that address emissions at the source, particularly at low frequencies. This paper analyzes the CM filter volume reduction when using two CM mitigation techniques acting at the source, namely Spread Spectrum Modulation (SSM) and the Delay Compensation Technique (DCT). The considered techniques are implemented on a WBG traction power inverter and the volume reduction of the CM EMI filter is evaluated through computer simulations.

Abstract
Switching converters require effective EMI filters to comply with conducted emission regulations. However, these filters often pose significant challenges, being expensive, bulky and heavy. The situation is further exacerbated with the latest generation of converters, utilizing WBG semiconductor devices, which operate at higher switching frequencies. Reduction of the filter size can be achieved through conducted EMI mitigation techniques that address emissions at the source, particularly at low frequencies. This paper analyzes the CM filter volume reduction when using two CM mitigation techniques acting at the source, namely Spread Spectrum Modulation (SSM) and the Delay Compensation Technique (DCT). The considered techniques are implemented on a WBG traction power inverter and the volume reduction of the CM EMI filter is evaluated through computer simulations.File | Dimensione | Formato | |
