Inductive pulsed power supply (IPPS) is considered as an alternative to capacitive one due to its higher energy density. An opening switch is necessary for an IPPS because it interrupts the charging circuit and transfers the stored energy to the load. A major technical challenge inherent to the IPPS is the overvoltage across the opening switch, i.e., the open-circuit voltage. Moreover, obtaining a larger current, especially with a steeper rising edge, will further increase the open-circuit voltage. A novel IPPS based on a three-winding pulse transformer, consisting of two primary windings and one secondary winding, is presented in this article to improve the output current and reduce the open-circuit voltage. The two primary inductors adopted a parallel switching scheme, namely, series charging and parallel discharging. Its working principle is analyzed first in detail. The theoretical analysis and simulation results have verified the superiority of the novel IPPS in improving the output current and reducing the open-circuit voltage.

由并联开关方式的三绕组脉冲变压器构成的新型感应脉冲电源

感应式脉冲电源 (IPPS) 因其较高的能量密度而被认为是电容式电源的替代品。IPPS 需要一个断开开关，因为它会中断充电电路并将存储的能量传输到负载。IPPS 固有的主要技术挑战是断开开关两端的过电压，即开路电压。此外，获得更大的电流，特别是上升沿更陡峭，会进一步增加开路电压。本文提出了一种基于三绕组脉冲变压器的新型 IPPS，由两个初级绕组和一个次级绕组组成，旨在提高输出电流并降低开路电压。两个初级电感采用并联开关方案，即串联充电和并联放电。首先详细分析其工作原理。理论分析和仿真结果验证了新型IPPS在提高输出电流和降低开路电压方面的优越性。
