| 摘 要： | 基于高变比脉冲变压器开展全固态调制器研究,输出电压为70kV、输出脉冲为200μs。研究了次级均匀绕制时环形结构脉冲变压器初次级间分布电容,给出了初次级间等效分布电容与静态分布电容的关系。在此基础上,从能量存储角度推导了次级非均匀绕制时初次级间等价分布电容与静态分布电容的关系表达式。基于理论分析对设计研制的脉冲变压器分布电容开展了实验研究,结果表明,采用非均匀绕制方式脉冲变压器动态分布电容减小30%,在脉冲变压器变比为1∶100时实现输出脉冲前沿2.5μs,过冲4.3%。

| Abstract: | The solid state modulator based on high ratio pulse transformer which utilizes nouniformity secondary to output 70 kV for 200 s is discussed. The stray capacitances of the annular pulse transformer are systematically analyzed. The relationship between static stray capacitances and equivalent stray capacitances when secondary is uniformity distribution is also presented. Furthermore, the analytic expression of the equivalent stray capacitances when secondary is nouniformity distribution is discussed. The experimental result shows that the equivalent stray capacitance reduces 30% when secondary is nouniformity distribution. The high voltage pulse with 2.5 s rise time and 4.3% overshoot can be achieved when the ratio of pulse transformers with nouniformity distributed secondary is 1∶100. |
