N2 - —With the rapid development of switching frequency and power density of high-density power supply (HDPS), the radiated electromagnetic interference (EMI) of converters is becoming increasingly severe. Different from traditional radiated EMI scalar model, the paper established an improved radiated EMI analysis model for power converters based on modeling for the spatial electromagnetic field of equivalent antenna. Through the improved model, the paper studied the spatial distribution of radiation gain and the vertical and horizontal polarization of radiated EMI for a FFC-LLC power module. The variation pattern of the vertical and horizontal polarization components of radiated EMI obtained by the improved model is consistent with actual situation. The improved radiated EMI analysis model accurately estimates radiated EMI in most research frequency band.
