Abstract: The impedance of the power system is an important parameter to measure the stability of the DC power system, which has great practical significance for the design and stability analysis of the power system. This paper proposes a power supply impedance test method based on the rate response analyzer, and designs a voltage-controlled current source adapted to the frequency response analyzer, which can test the power supply impedance. The test system has simple structure, convenient operation and high test accuracy.
