摘要
介绍一种计算机控制模式电磁搅拌器控制系统,其特点在于计算机设置和处理搅拌器所需的参数,并通过脉宽调制和驱动回路实现交—直—交电源的转换,为搅拌器提供稳定和精确的电流和频率参数;逆变装置采用大功率模块并联技术分立安装,容易获得大电流的输出且维护方便.
This paper introduced a computer control system for electromagnetic stirrer （EMS）. It fea- tures that the operational parameters can be set by computer. AC - DC - AC conversion can be achieved by PWM and drive circuit. Stable and accurate current and frequency can he supplied for EMS. Invertors are separately installed with parallel connection of large power modules. Large current can be easily ob- tained with easy maintenance. 7figs. , 10refs.
