摘　　要：为了研究大尺度等离子体激励器和调整电源电感、电容的情况,笔者对等离子体气动激励系统的电特性进行了实验研究,得出等离子体气动激励系统的电感和电容是影响电特性的关键因素。实验结果表明,一定的电源输入电压下,减小电源电感或串联电容分压器,等离子体气动激励系统的谐振频率、电源输入电流和放电电流增大,等离子体气动激励器的放电电压基本保持不变;随着电源频率的增大,等离子体气动激励系统放电有3个典型的方式,电源频率小于谐振频率时,放电电流波形有突变;随着电源频率增大,激励系统的感性不断增大,放电电流增大,电流突变消失;电源频率大于谐振频率后,电容将电压的高次谐波滤掉,放电电流减小。Experimental investigation of the electric characteristics of plasma aerodynamic actuation system is conducted. The inductance and capacitance of plasma aerodynamic actuation system are key factors which affect the electric characteristics plasma aerodynamic actuation system. When inductance of a power supply is decreased or a capacitance is connected in series to the power supply under a certain input voltage, the resonance frequency of plasma aerodynamic actuation system, input current of power supply and discharge current increase, while the discharge voltage of plasma aerodynamic actuator remains stable. With frequency ascending under a certain input voltage of power supply, there exist three typical discharge ways in the plasma aerodynamic actuation system： when frequency of power supply is less than the resonance frequency of the actuation system, there is a break in the discharge current waveform; when the frequency increases, the actuation system＇s inductance and discharge current arise continually without a discharge current break; when the power supply frequency is higher than the resonance frequency of the actuation system, the capacitance filters higher-order voltage wave to reduce the discharge current.
