中文摘要: 采用了由微处理器控制的负反馈──连续采样数据反馈控制方式,可以提高放大电路的稳定性,同时又明显改善闭环增益在输出级采用限流式推挽功率放大电路,可以实现0~70V电压直接放大,而不必加输出变压器,在一定程度上改善了输出波形的失真率。文中还给出了主要测试结果。
Abstract:This paper introduces a voltage amplifier for high-accurate signal generators. Applyingthe negative feedback and continual sample data feedback mode controlled by amicroprocessor, it can increase the gain with feedback and improve the stability of the amplifier.Some important experimental results are presented in this paper.
