Impedance Analysis of Single-Phase PFC Converter in the Frequency Range of 0–150 kHz
Abstract
This paper investigates the influence of power converter impedance for below 150 kHz frequency range from power quality and EMI performance perspectives. Moreover, feasible solutions to maintain the performance of the power converter are analyzed. For this purpose, the analytical closed loop impedance model of a single-phase PFC converter is derived. Then, a suitable experimental impedance measurement approach and hardware requirement is proposed and the derived closed loop impedance model is validated experimentally at different operating conditions and control bandwidth. The investigations are performed based on different control, filter configurations and operating conditions.
