混合磁芯脉冲电压耦合器的宽频带电路仿真模型

Wide-band circuit simulation model of pulsed voltage couplers made of hybrid magnetic cores

采用阻抗不同的AB两种磁芯,提出了两种混合AB磁芯的脉冲电压耦合器模型,即AA+BB和A+B两种混合磁芯设计方案,然后建立了电路仿真模型进行分析;最后,制作试验电路对该耦合器进行高压电容器放电试验。高压试验结果表明,混合磁芯耦合器的仿真电压和电流波形与试验波形基本吻合,从而验证了电路仿真模型的正确性。

Using A and B two kinds of magnetic cores with different impedances, two models of pulsed voltage couplers made of A,B hybrid magnetic cores were proposed, which were two kinds of AA+BB and A+B. Then the circuit simulation models were built and analyzed. Finally, the high voltage capacitor discharging tests on the coupler were conducted by using the fabricating test circuit. The test results show that the simulation waveforms of voltage and current coincide with those of the tests. The validity of circuit simulation model is verified.
