摘要
利用脉宽调制技术, 设计了一台为高功率微波源提供导引磁场的脉宽调制型励磁电源, 它可在励磁线圈中产生一定持续时间的准稳态强磁场。励磁电源的储能部分采用容量15 F、最高充电电压800 V的储能密度较高的超级电容器, 最大储能为4.8 MJ, 内阻小于0.25 Ω。在储能电容充电645 V的情况下, 对电感约为60 mH、电阻约0.40 Ω的励磁线圈进行了励磁实验, 获得了持续时间为1.9 s、幅值为900 A准稳态电流, 电流波动幅度为5%, 对应线圈中的最大轴向磁场为2.2 T。实验结果与理论计算基本一致, 表明所研制的励磁电源达到了设计要求。
Abstract
Guiding magnetic fields are necessary for some high-power microwave (HPM) sources, and the usual way to generate them is to apply capacitor discharge to solenoids. In the paper, a power source using the pulse width modulation(PMW) technique is designed, which can drive solenoids to generate a quasi-steady strong magnetic field with certain duration. A 15 F super-capacitor bank with the maximum charge voltage of 800 V, the maximum energy storage of 4.8 MJ and an internal resistance of less than 0.25 Ω is used as the energy storage part of the source. In experiments, when charged to 645 V, the source can generate a quasi-steady current of 900 A with a duration of 1.9 s on a solenoid with 60 mH inductance and 0.40 Ω resistance, and the corresponding axial magnetic field is 2.2 T at the maximum.
