摘　　要：针对现有的放大电路输出功率小、输出电压幅值较低的问题,设计了一种高精度放大隔离电路,该电路包括供电模块、三角波驱动模块和信号调理模块三部分,将的三角波信号经高压放大器放大,后经信号调理电路可实现大功率的三角波电压信号输出和双量程电流的隔离输出,并通过上位机进行采集,输出信号测试结果精度均在0.2%以内。Aiming at the problems of small output power and low output voltage amplitude of the existing amplification circuit,a high-precision amplification and isolation circuit is designed.The circuit includes three parts:power supply module,triangular wave driving module and signal conditioning module.The triangular wave signal is amplified by the high-voltage amplifier,and then the high-power triangular wave voltage signal output and the isolation output of double range current can be realized by the signal conditioning circuit,and the data can be collected by the upper computer.The accuracy of output signal test results is within 0.2%.
