Improving 9-150 kHz EMI Performance of Single-Phase PFC Rectifier

In order to improve the Electromagnetic Interference (EMI) performance of grid-connected power electronics converters within the new 9-150 kHz frequency range, this digest investigates feasible solutions through modifying the EMI filter and applying spectral shaping method. The proposed solutions are validated based on a 1 kW single-phase Power Factor Correction (PFC) rectifier prototype. Moreover, frequency domain modeling approach is utilized as a virtual-oriented methodology in order to analyze the converter behavior and provide fast prototyping.
