摘要: 介绍了一种基于空芯变压器的三谐振高压脉冲变压器。通过对三谐振脉冲变压器无损等效电路的理论分析,给出了在回路本征频率为1∶2∶3时,电路各参数的关系及输出电压解析表达式,由此可知在此条件下变压器次级高压绕组上的最大电压与负载电容上最大电压比为0.36∶1。根据理论结果,设计了一组参数进行了电路模拟,证明了理论分析结果的正确性,可用于三谐振脉冲变压器的设计。并模拟了变压器耦合系数、调谐电感、调谐电容、初级电容及负载电容等参数变化对装置输出电压及能量传输效率的影响。由模拟结果可知,调谐电感和调谐电容在-10%~10%范围,初级电容在0~10%范围以及负载电容在-10%~0范围内变化对装置的性能影响不大,该变压器较容易实现工程化。Abstract: A triple resonance pulse transformer, based on an air-cored transformer, is described. By analyzing the triple resonance pulse transformer lossless circuit, the analytical expression for the output voltage and the relation of the circuit parameters are presented when the normal-mode frequencies are in the ratios of 1∶2∶3. In this case, the ratio of the peak high voltage winding’s voltage to the peak output voltage is 0.36. According to the results of theoretic analysis, the circuit parameters of a triple resonance pulse transformer such as coupling coefficient, tuning inductor, tuning capacitor, primary capacitor, load capacitor are simulated. The simulation results show that the output voltage and the energy efficiency have few variations when the tuning inductor and the tuning capacit
