    摘要:

    随着在材料表面改性、粉尘捕集以及电力设备检测的广泛应用,高压脉冲电源朝着小巧、控制简单的方向发展。目前的高压脉冲电源由于固态开关驱动信号需要进行高压隔离,造成体积庞大、控制系统复杂。为精简系统的体积和重量,提出了一种基于串联固态开关的自触发式高压脉冲电源的拓扑结构,仅需一个控制信号即可控制系统所有固态开关,实现高压脉冲输出。基于该拓扑结构在通用电路分析软件PSPICE中仿真了6级基于串联固态开关的自触发脉冲电源,结果表明所提新型电路拓扑直流电源工作电压为1500 V时,系统输出脉冲电压幅值约为9 kV,脉冲宽度约为100~200 ns。该结构简化了高压脉冲电源控制系统,减小了系统体积和质量,降低了生产成本且无需考虑控制信号高压隔离,大幅提升了功率密度。

    Abstract:

    With the widespread application of high-voltage pulse power supplies in material surface modification, dust capture and power equipment detection, high-voltage pulse power supplies are developing towards compactness and simple control. Currently, high-voltage pulse power supplies require high-voltage isolation due to solid-state switch drive signals, resulting in large volume and complex control systems. In order to simplify its volume and weight, a topology structure of self-triggered high-voltage pulse power supply based on solid-state switches in series is proposed, which requires only one control signal to control all solid-state switches in the system and achieves high-voltage pulse output. Finally, based on this topology, a 6-stage self-triggered pulse power supply based on solid-state switches in series is simulated in general circuit analysis software (PSPICE). The results show that at an operating voltage of 1500 V in DC power supply, the proposed new circuit topology delivers an output pulse voltage amplitude of approximately 9 kV with a pulse width of 100~200 ns. The proposed structure simplifies the control system of high-voltage pulse power supply, reduces the system volume and weight, lowers production costs, and eliminates the need to consider high-voltage isolation of control signals, thereby greatly improving power density.
