脉宽调制型正弦波铃流信号源的研究
Study of PWM sinusidal bell current signal source
【摘要】 本文介绍了采用新的脉宽调制原理和微电脑技术,研制出的25赫正弦波铃流源.文末对该铃流源做了较客观的估价,并提出改进设想和预期达到的目标.
【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.
