摘要
升流器电源将A/D、D/A技术、SPWM技术、逆变技术等综合应用,根据数字输入量改变引起升流器输出电流的变化,以及系统的响应时间,结合特定的自动升流PID控制算法,较理想地实现了试验中的平稳升流和稳流。该电源运用数字波形合成技术,输出稳定电流的频率宽,频率范围为:30Hz^2500Hz,输出正弦波电压范围:0~150V。该电源适用于电流互感器(CT)的谐波测试试验,以及其它需要使用变频调压电源的试验场合。宽频升流器电源采用LCD屏汉字显示,具有完善的试验功能和良好的人机对话界面。在实际使用中效果良好。
We use the techniques of A/D、D/A、SPWM、inverter circuit and so on to broadband rising current source,according to the changes of high-current arising from the input of D/A and the system's response time, the combination of specific PID algorithm, to achieve a better current test of the automatic step-up and remain stable. This kind of broadband rising current source has perfect test function and human-computer interaction, and produce good results in actual use.
