Abstract

DC power supply impedance is one of performance parameter of power supply, some commercial products list the output impedance in its specification manual. This paper analyzes the definition of dc power supply impedance, summarises its characteristic, review the development of measurement technology of dc power supply impedance at present. A new measurement system based on digital impedance bridge is put forward here. The difficult and under studied problem are also put forward here.
