摘要
为满足高压双极性脉冲产生臭氧的实验需求,研制了1种新型的全固态高压双极性脉冲叠加器。该结构对全桥结构的脉冲叠加器进行了改进,减少了开关使用数量,通过控制主电路中MOSFETs的驱动信号,实现双极性高压脉冲的输出。对电路的结构设计、容性负载下的工作过程、参数设计进行了阐述分析,并利用Pspice软件对电路的可行性进行了仿真验证。最后搭建了1台9级实验样机,实验表明:该双极性高压脉冲源的截尾机制可有效解决脉冲拖尾问题;电容负载时,采用改进后的控制策略避免了偏压的产生,脉冲源可稳定输出±4k V、最小脉宽600 ns的方波窄脉冲;在DBD负载下频率最高可达12 kHz,为开展高压脉冲产生臭氧的实验提供了硬件支持。
In order to meet the experimental demands for ozone generation from high-voltage bipolar pulses, a new type of all-solid-state high-voltage bipolar pulsed adder was developed. In the structure, the full-bridge pulse adder is improved and the number of switches is reduced, and the output of bipolar high-voltage pulses can be realized by controlling the driving signals of the MOSFETs in the main circuit. Moreover, the structure design of the circuit, the working process and the parameter design under the capacitive load were expounded and analyzed, and the feasibility of the circuit was verified by the Pspice software. Finally, a laboratory prototype was assembled with 9 stages. The experimental results show that the truncation function of the bipolar high-voltage pulse source can effectively solve the problem of pulse tailing;when using capacitive load, the improved control strategy avoids the generation of bias voltage, and the pulse source can output ±4 k V bipolar rectangular wave narrow pulses with 600 ns positive/negative pulse widths; the pulse source frequency can be up to 12 kHz under DBD load, which provides a hardware support for the experiment of generating ozone by high voltage pulse.
