摘要

Using AandB two kinds ofmagnetic coreswith different impedances, two models ofpulsed voltage couplers madeofA,Bhybrid magnetic coreswere proposed, which weretwo kinds ofAA+BB and A+B. Then the circuit simulation models werebuilt and analyzed.Finally, thehigh voltagecapacitor discharging testson the coupler were conducted by using the fabricating test circuit.The test resultsshow that the simulation waveforms ofvoltage and current coincidewith thoseofthetests.Thevalidityofcircuit simulation modelis verified.%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。
