摘要
为产生重复频率脉冲磁场的螺线管,研制了一种新型的初级能源,它采用半桥串联谐振恒流充电拓扑结构,可在0-2.5 kV范围内实现输出可调,最大平均充电功率达4.7 kW。该电路最大特色在于无需使用外加谐振元件,只利用变压器的漏感和半桥桥臂电容组成谐振元件。简要分析了电路的工作过程,给出了电路参数设计方法和设计实例,并进行电路仿真和初步实验研究,结果表明,该设计基本达到要求。最后,进行了带螺线管负载的实验研究,实验证明该能源在重复频率10 Hz条件下运行稳定可靠。
A repetitive pulsed magnetic fields serving as the guiding magnetic field for the repetitive high-power microwave source has been proposed,which makes the source compact with low loss and small heat.A primary energy source for solenoid which can output rep-rate pulsing magnetic field is developed.It adopts half-bridge topology with series resonant constant-current charging technology and the output is adjustable,from 0 to 2.5 kW.The average power can reach 5 kW at most.Without adding other resonant components,the circuit makes full use of the transformer leakage inductance and bridge-arm capacitance so as to reduce the influences of the transformer parameter.The operating process of the circuit is analyzed briefly.The parameters of the power supply are calculated and a designed example is presented.The emulation and experiments are given and experimental results are in accordance with the calculation request.The primary energy source is experimentally investigated across a solenoid and it can work steady at 10 Hz rep-mode.
