The paper introduced the functions of digital voltage phase-shifting and amplitude adjustment based on microcomputer ARM. It can realize phase-shifting of voltage wave signal between 0~360 degree by using the method of RAM round alignment,and it can hold the line of frequency in the process of phase-shifting. The voltage amplitude of phase-shifter output can be adjusted,and output certain power. The equipment can be used in experiment teaching of relay protection and microcomputer relay protection as Experimental Teaching Platform in university.
