摘　　要：在连续式等离子体电源的基础上,研制出微秒脉冲等离子体电源,增加了脉冲宽度、脉冲相位和脉冲频率等调制方式,丰富了等离子体实现流动控制的手段。给出了微秒脉冲电源的总体设计方案,对电源硬件电路及控制软件做了介绍,并提出了电源运行的具体指标。通过一系列静止大气下的流动控制实验,对比采用脉冲调制和连续放电时流场诱导效果的差异,证明脉冲等离子体电源比连续式等离子体电源性能有较大提升,且具有低耗能,工作稳定可靠等特点,应用前景广阔。In this paper,a self-made microsecond pulse plasma power supply was introduced,which was based on continuous plasma power supply.The power supply increased the control methods of pulse-width,phase and pulse-frequency modulation,and enriched the means to achieve flow control by plasma.The overall design scheme,the hardware circuit and control software of the microsecond pulse plasma power supply were introduced in this paper,and the working parameter of the power supply was also proposed.A series of flow control experiments on circular cone without air flow was done using this power supply.Comparison of the flow fields which were induced by pulse modulation and continuous discharge was done to acquire the operational characteristics of the power supply.The results show that the power supply has a more powerful performance than the continuous,and has prospects of stable,reliable,broad application and low energy consumption.
