Abstract: |
In this paper,using a new principle of PWM and the teehnique of storage system in a microcomputer are deseribed,and a 25Hz sinusidal bell current source has been developed.The bell current source is objectively evaluated.Finally,improvement conception and expected attainment target are proposed. |
