摘　　要：为了解决连续脉冲电源的电流脉冲波尾冗长等问题,提出了新型的基于超导脉冲变压器的连续脉冲电源放电拓扑,该拓扑通过四个晶闸管及逆流电容组成的桥式电路实现工作模态切换,当负载电流脉宽达到预期要求后,利用逆流电容放电改变脉冲变压器二次侧的电感电压极性,实现负载电流脉冲快速关断,未及时释放的能量被回收至一次侧电感,有效提高了能量利用效率。仿真结果表明:该电路能实现负载电流波尾的可控关断,并且在脉冲形成后回收一定的剩余能量。经过与其他拓扑的对比验证,新型拓扑在保持优良电气性能的同时,结构简单、成本较低,具备应用于电磁连续发射系统的潜力。In order to solve the problem of long current pulse wave tail of continuous pulse power supply, a new discharge topology of the power supply was proposed based on superconducting pulse transformer, realizing the work mode switching through a bridge circuit composed of four thyristors and counter-current capacitors.When the load current pulse width reached the expected requirement, the inductor voltage polarity on the secondary side of the pulse transformer was changed by using the counter-current capacitor discharge to realize quickly turned off of the load current pulse, and the energy not released in time was recycled to the primary side inductor so as to effectively improve the energy utilization efficiency. The simulation results show that the circuit can achieve controlled shutdown of the load current wave tail and recover a certain amount of residual energy after the pulse is formed. After comparison with other topologies, the new topology is verified to have the potential to be applied to electromagnetic continuous emission systems with simple structure and low cost while maintaining excellent electrical performance.
