摘要

摘要: 针对空间磁场环境模拟线圈磁感应强度0~20 Gs连续可调,磁场稳定度优于1%的要求,采用前级电压源与后级电流源串联的主电路拓扑结构,结合电压双闭环控制和电流闭环负反馈控制的方法,实现了稳定的电流输出,减小了功率金属-氧化物半导体场效应晶体管(MOSFET)的功耗,提高了恒流源的效率.测试结果表明:恒流源输出电流0~10 A连续可调,霍姆赫兹线圈中心磁感应强度能达到20 Gs的设计要求,电流稳定度优于0.1%,磁场稳定度优于1%.

Abstract: To reach the requirements that the space environment simulation coil's magnetic induction intensity can continuously adjust from 0 to 20 Gs, and the magnetic field stability can be better than 1%, main circuit topology structure using a voltage source in series with a current source, combined with the voltage double closed loop control and the current closed loop negative feedback control methods, achieved a stable current output, reduced the power consumption of the metal-oxide-semiconductor field-effect transistor (MOSFET), and improved the efficiency of the constant current source. The test results show that the constant current source output current ranges from 0 to 10 A, Helmholtz coil's center magnetic induction intensity can reach the design requirements of 20 Gs, the current stability is better than 0.1%, and the magnetic field stability is better than 1%.
