在电机控制系统中,设计者可通过周密分析获得理想的性能,即使开始看上去某些元件不合适。对于来自电流传感器的±5 V输出信号,则需要使用双电源(±12 V)的模数(A/D)转换器,TI公司推出的ADS7864型A/D转换器拥有同样效能,并给出了相关闭环电流互感器的应用。
In motor control systems, designers get the right performance through granular analysis, even though some components may not seem appropriate at first. The ± 5 V output signal from the current sensor requires a dual supply (± 12 V) analog-to-digital (A / D) converter. TI’s ADS7864 A / D converter has the same performance and gives The relevant closed-loop current transformer applications.
