| 摘 要： | 空间等离子体环境模拟与研究装置用于在地面模拟空间磁场和等离子体环境,需要在3.5μH电感、0.8 mΩ电阻的环向场线圈负载上产生前沿130μs、降流时间不大于1600μs、峰值260 kA的脉冲电流,因此设计了一套模块化的电容器型放电电源。针对相对较小电感的负载,根据设计要求的放电波形和开关组件通流能力,考虑负载短路故障的情形,给出了保护电感、优化的模块数量等回路参数计算方法。进一步采用传输电缆作为能量传输,同时将电缆寄生电感作为保护电感的方案,研制了一套由4个模块组成的放电电源。研究结果表明,本文给出的电路理论计算结果与设计要求一致,放电试验进一步证明电源设计满足设计放电波形要求。

| Abstract: | The space plasma environment research facility (SPERF) is used to simulate the space magnetic field and plasma environment on earth. To generate a pulse current across the 3.5 μH, 0.8 mΩ toroidal field (TF) coils, a modularized capacitor-based pulsed power supply (PPS) was built. The rise time of the pulse current was approximately 130 μs, and the peak current was 260 kA. To avoid damage to the PPS when the coil load was short-circuited, the circuit parameters of the PPS, such as the number of modules, the inductance of the protection inductor, were calculated based on current waveform requirements and the maximum ratings of the thyristor switch. Since the inductance of the coil load was relatively small, the output cable was used as both the transmission line and the protection inductor, and a 4-module PPS was designed and fabricated. Simulation results indicate that the 4-module PPS design meets the demand of both the current waveform and the maximum ratings of the thyristor switch, and the discharge test further proves the output current waveform of the PPS agrees with the simulation results. |
