For the air - core pulse transformer has no magnetic material to form the magnetic loop , its coupling coefficient and energy efficiency is lower . in order to improve its property , partial magnetic material is inserted in air - core spiral strip transformer . this method not only results in better property of transformer , but also reduces the bulk of transformer 本课题设计的变压器是在带绕式空芯脉冲变压器中加部分磁芯材料以提高变压器耦合系数,进而提高其能量传输效率,此方法弥补了空芯变压器耦合系数低的缺点,并且可以使变压器小型化,因此对部分磁芯脉冲变压器理论和试验的进一步研究具有重要的理论和实践意义。
