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1∶2∶3时,电路各参数的关系及输出电压解析表达式,此条件下负载电压最大值为空芯变压器次级高压输出电压的2.77倍。根据理论分析及电路模拟的结果,提出了适用于三谐振脉冲变压器的设计方法——迭代模拟法,并采用迭代模拟的方法在研制的空芯变压器基础上研制了一台基于三谐振脉冲变压器的脉冲功率源,进行了实验研究。实验结果表明:所研制的三谐振脉冲变压器输出电压的最大值可以达到锥形高压绕组输出电压的2倍,系统最大工作电压约为600kV,与理论分析的结果相吻合,说明将任意一台双谐振脉冲变压器改造成三谐振脉冲变压器具有可行性。
The triple resonance pulse transformer is a new type of pulse transformer,which is based on air-cored transformer.The voltage across the pulse transformer is significantly less than the output voltage;instead,the full output voltage appears across the tuning inductor.By analyzing the pulse transformer＇s lossless circuit,the analytical expression for the output voltage and the relation of the triple resonance circuit parameters are presented for the eigen frequency ratio of the circuit being 1∶2∶3,and the maximal ratio of peak load voltage to peak transformer voltage is 2.77.Then a design method for the triple resonance pulse transformer,iterative simulation method,is presented.A pulse power generator based on the triple resonance pulse transformer developed from an air-cored transformer is developed accordingly.The experimental results indicate that the ratio of the peak output voltage to the peak voltage on high voltage winding is 2 and the peak output voltage of the triple resonance pulse transformer is 600 kV.The theoretical and experimental results agree well with each other.Therefore,any double resonance pulse transformer may be developed into a triple resonance pulse transformer.
