Abstract
This paper introduces and compares three impedance estimation techniques: FFT, PSD and CWT. The impedance of proposed system is calculated by using the injected step current transient and the measured voltage response. Both steady and noisy situation is simulated by Matlab/Simulink and the characteristics of each impedance analyzing method are demonstrated by the achieved impedance results.
