基于EWB的交流恒流源设计

AC Current Source Design Based on EWB

在测量系统中,使用电源的稳定、精确是保证测量电路结果准确无误的重要因素。文中设计了一个压控交流恒流放大系统,该电路系统由恒流放大电路、功率推动电路和中点伺服电路三级构成,具有恒流特性较好、反馈电阻可调的优点。然后使用EWB5.0进行仿真,验证了该系统的有效性。

In the measurement system,using the power supply stable,accurate measurement results to ensure the accuracy of the important factors.Article designed a voltage controlled constant current amplification system exchange.The circuit system consists of constant-current amplifier,the power to promote the mid-point servo circuit 3 to promote and composition,with constant current characteristics of good feedback on the advantages of adjustable resistance.And practical EWB5.0 simulation to verify the validity of the system..
