Abstract:
This paper presents a method of impedance analysis in power electronic systems during operation. The switching behavior of power electronic components causes harmonic excitation in a system. These harmonics in voltage and current are analyzed with a polyphase filter bank. Afterwards they are used to calculate the system’s frequency dependent impedance. The method is validated with simulations and verified by measurements of a real power converter. The results give incentive for further researches.
