Abstract

The generation of plasma by DBD has the advantages of low environmental requirements, simple operation, wide industrial applications, and the ability to stably generate low-temperature plasma. The high-frequency and high-voltage AC power supply is the main component of the DBD device. To achieve an adjustable frequency of the output voltage of high-frequency and high-voltage power supplies and improve the voltage stability performance of the power supply, this paper proposes a design scheme of a high-voltage and high-frequency AC power supply for DBD based on SG3525A, which introduces the system composition, control strategy, hardware circuit, simulation, and experimental results of the driving power supply in detail. The driving power supply adjusts the output voltage through a PWM signal generation circuit, an RCD absorption buffer circuit, and a power factor correction DC power supply. Under a DBD load with an equivalent capacitance of 48pF, the peak output voltage of the driving power supply is 50 kV, and the output frequency is up to 40 kHz. The experimental results show that the driving power supply meets the driving requirements of high voltage, high frequency, and excellent voltage stabilization performance for DBD.

基于 SG3525A 的用于介质势垒放电 (DBD) 的 50kV/0-40kHz 高压交流电源设计方法

DBD 法产生等离子体具有对环境要求低、操作简单、工业应用广泛、可稳定产生低温等离子体等优点。高频高压交流电源是 DBD 设备的主要组成部分。为实现高频高压电源输出电压的频率可调，提高电源的电压稳定性能，本文提出了一种基于 SG3525A 的 DBD 用高频高压交流电源设计方案，详细介绍了驱动电源的系统组成、控制策略、硬件电路、仿真及实验结果。驱动电源通过 PWM 信号发生电路、RCD 吸收缓冲电路和功率因数校正直流电源调节输出电压。在等效电容为 48pF 的 DBD 负载下，驱动电源的峰值输出电压为 50 kV，输出频率高达 40 kHz。实验结果表明，该驱动电源能满足 DBD 的高电压、高频率和优异稳压性能的驱动要求。
