摘　　要：介质阻挡放电(DBD)技术作为一种新兴的空气消毒手段,因其能够在常温下产生低温等离子体,并有效杀灭空气中的细菌和病毒,受到了广泛关注。为满足DBD技术的应用需求,完成了DBD放电脉冲电源的研制。该电源采用倍压电路对前级电容进行充电,不仅保证了IGBT(绝缘栅双极型晶体管)的零电流关断,还防止了后级短路可能对固态开关造成的击穿风险。通过将脉冲变压器的电压提升作用与磁开关的脉冲陡化作用相结合,实现了负载电压的快前沿、高峰值输出。这一设计不仅减轻了前级系统的负担,还显著提高了系统的寿命和重复工作频率。实验结果表明,该电源的负载输出电压峰值可达27 kV,脉冲宽度为650 ns,脉冲前沿时间为60 ns,且重复频率在0~500 Hz范围内连续可调。Dielectric barrier discharge(DBD)technology,an emerging method for air disinfection,has drawn considerable interest due to its capacity to generate low-temperature plasma at ambient temperatures,thereby effectively neutralizing airborne bacteria and viruses.To cater to the practical requirements of DBD technology,the development of a DBD discharge pulse power supply has been successfully completed.This power supply incorporates a voltage doubling circuit to charge the front-stage capacitor,not only ensuring the zero-current shutdown of the IGBT(insulated gate bipolar transistor)but also mitigating the risk of breakdown potentially caused by short circuits in the back-stage to the solid-state switch.By leveraging the voltage amplification of a pulse transformer in conjunction with the pulse sharpening effect of a magnetic switch,the system achieves a rapid leading edge and a high peak load output voltage.This design not only alleviates the load on the preamplifier system but also substantially enhances the system's lifespan and operational frequency.Experimental data reveal that the peak load output voltage of this power supply can reach 27 kV,with a pulse width of 650 ns,a pulse rise time of 60 ns,and a continuously adjustable repetition frequency ranging from 0 to 500 Hz.
