摘　　要：针对直线感应加速器校正线圈的供电需求,用悬浮负载法和接地负载法研究了基于功率运算放大器的电压控制型恒流源。从理论计算、数值模拟和实验方面研究和对比了两种压控恒流源的工作原理、工作特性和输出结果。试验结果表明,在两种恒流源上都能够得到预定的电流输出,悬浮负载恒流源的输出更加稳定,能够满足将来的工程运用要求。In the linear induction accelerator, the power supply of rectifier loop is constant current sources. This article studied two kinds of voltage controlled constant current sources（VCCS） with operational amplifiers based on floating load and grounded load. From theory, simulation and experiment, their differences in configuration, operation character and output were comparatively studied. The results point out that the two kinds of VCCS can both produce the output in anticipation, and the floatingqoad VCCS can provide a more steady current output, fulfilling the future engineering requirements.
