摘要:

用Matlab软件对大气压均匀辉光放电等离子体(OAUGDP)激励器系统的电特性进行了仿真。在仿真模型中,等离子体放电被建模成一个电压控制的电流源:当加在气隙上的电压超过等离子体产生电压时,该受控电流源接通;电流源的输出电流和所加电压之间遵循幂律。建立了一个OAUGDP激励器系统中等离子体放电的电路模型。仿真结果与实际激励器系统的实验数据很吻合。仿真结果表明,在不同的运行条件下,放电电流与电压之间遵循不同的指数幂律,仿真放电电流波形也不同。

Abstract:

Simulation of the electrical characteristics of atmosphere uniform glow discharge plasma (OAUGDP) reactor system has been conducted with the Matlab software. Plasma discharge is modeled as a voltage-controlled current source: the discharge current outputs and follows a power law of the applied voltage when the voltage across the gap exceeds the plasma initiation voltage. Simulation results agree well with experimental data. It is also found that the voltage power laws to describe OAUGDP are dissimilar for different operating regimes, and therefore the discharge current waveforms are different.
