双层同轴结构的方波直线变压器驱动源模块设计
Design of Square Pulse Linear Transformer DriverModule With Two-Layer Coaxial Structure
摘要
Abstract
Square pulse output can be generated by paralleling harmonic bricks into the main bricks in fast linear transformer driver (FLTD).A novel square pulse FLTD module with the peak current of 1 MA is designed.Two layers coaxial structure is introduced in the FLTD module with the outer layer containing the main bricks and the inner layer containing the harmonic bricks of low inductance.Based on the requirements of 20 kJ KrF laser driver, the parameters of magnetic cores, capacitors and secondary transmission line are estimated.The square FLTD module is 2.6 m in diameter and 0.23 m in thickness, including 36 main discharge bricks, 16 third harmonic bricks and 8 fifth harmonic bricks.PSPICE circuit model is established, the simulation results show that FLTD module output current waveform is approximate square pulse with a peak current of 950 kA, rising time of 46 ns, and the flat top width of 217 ns over 90% peak current.关键词
