Description
技术领域technical field
本发明涉及高压脉冲电源技术领域，具体而言，涉及一种面向多个等离子体合成射流激励器同步放电应用的负极性高压脉冲电源。The invention relates to the technical field of high-voltage pulse power supply, in particular to a negative polarity high-voltage pulse power supply for synchronous discharge application of multiple plasma synthetic jet actuators.
背景技术Background technique
流动控制可分为被动控制和主动控制两大类，主动控制是在流场中直接注入合适的扰动模式和能量，使其与系统内流动发生某种相互作用实现控制，控制效果可根据实际工况进行自适应调节。合成射流作为一种全新的主动流动控制技术，无需气源供应系统，结构简单、响应快、工作频带宽和零质量流率等特点，在流动控制领域具有广泛应用。随着等离子体技术的飞速发展，等离子体合成射流技术在高速流场控制中有着极大的优势。Flow control can be divided into two categories: passive control and active control. Active control is to directly inject appropriate disturbance mode and energy into the flow field to make it interact with the flow in the system to achieve control. The control effect can be determined according to the actual work. self-adaptive adjustment. Synthetic jet, as a new active flow control technology, does not require an air source supply system, has the characteristics of simple structure, fast response, wide operating frequency and zero mass flow rate, and is widely used in the field of flow control. With the rapid development of plasma technology, plasma synthetic jet technology has great advantages in high-speed flow field control.
目前，产生等离子体合成射流的电源主要有以下几种：At present, there are mainly the following types of power sources for generating plasma synthetic jets:
法国宇航局研制了两种脉冲变压器型电感储能型和电容储能型的电源，将其应用于等离子体合成射流实验，实验发现：在间距为1.2mm的条件下，放电电压约为4.7kV，电感储能型电源的放电电流约为30A，电容储能型电源的放电电流约为250A(BelingerA,HardyP,BarricauP,etal.Influenceoftheenergydissipationrateinthedischargeofaplasmasyntheticjetactuator[J].JournalofPhysicsD:AppliedPhysics,2011,44(36):365201.)。其设计的电源在高压侧串联有限流电阻，这会使得电源的重复频率低、能量转换效率低。The French Space Agency has developed two kinds of pulse transformer type inductive energy storage type and capacitive energy storage type power supply, and applied them to the plasma synthetic jet experiment. The experiment found that: under the condition of a distance of 1.2mm, the discharge voltage is about 4.7kV , the discharge current of the inductive energy storage type power supply is about 30A, and the discharge current of the capacitive energy storage type power supply is about 250A (BelingerA, HardyP, BarricauP, et al. .). The designed power supply has a current-limiting resistor connected in series on the high-voltage side, which will result in low repetition frequency and low energy conversion efficiency of the power supply.
德克萨斯大学研制了一套面向等离子体合成射流应用的激励源，该激励源包括高压直流电源、储能电容、限流电阻、MOSFET开关等器件。在5mm间距下，放电点电压约为2.2kV，放电电流约为3A(NarayanaswamyV,RajaLL,ClemensNT.Characterizationofahigh-frequencypulsed-plasmajetactuatorforsupersonicflowcontrol[J].AIAAjournal,2010,48(2):297-305)。该装置结构相对零散，功率较小，产生的等离子体合成射流速度较低。The University of Texas has developed a set of excitation sources for plasma synthetic jet applications. The excitation sources include high-voltage DC power supplies, energy storage capacitors, current-limiting resistors, MOSFET switches and other devices. At 5mm spacing, the discharge point voltage is about 2.2kV, and the discharge current is about 3A (NarayanaswamyV, RajaLL, ClemensNT. Characterization of high-frequency pulsed-plasma jettactuator for supersonic flow control [J]. AIAAjournal, 2010, 48(2): 297-305). The structure of the device is relatively fragmented, the power is small, and the velocity of the plasma synthetic jet generated is low.
国防科技大学利用直流源和脉冲源配合研究三电极等离子体合成射流特性，实验发现利用两种电源的配合可以明显降低等离子体合成射流激励器的击穿电压(WangL,XiaZ,LuoZ,etal.Three-ElectrodePlasmaSyntheticJetActuatorforHigh-SpeedFlowControl[J].AIAAJournal,2013,52(4):879-882.)。但利用两台电源的配合增加了装置的复杂性，不利于实际应用。The National University of Defense Technology used a DC source and a pulse source to study the characteristics of the three-electrode plasma synthetic jet. It was found that the combination of the two power sources can significantly reduce the breakdown voltage of the plasma synthetic jet actuator (WangL, XiaZ, LuoZ, et al.Three -ElectrodePlasmaSyntheticJetActuatorforHigh-SpeedFlowControl[J].AIAAJournal,2013,52(4):879-882.). However, the cooperation of two power supplies increases the complexity of the device, which is not conducive to practical application.
空军工程大学利用磁压缩式纳秒脉冲电源研究等离子体合成射流的气动特性，脉冲源的输出电压最大50kV，频率最大为5kHz，上升沿20ns-30ns，半高宽50ns，实验中放电电压约为4.7kV，放电电流为20A(贾敏,梁华,宋慧敏,等.纳秒脉冲等离子体合成射流的气动激励特性[J].高电压技术,2011,37(6):1493-1498.)。此类电源的放电电流较小，不利于等离子体合成射流激励器腔体的加热。The Air Force Engineering University uses a magnetic compression nanosecond pulse power supply to study the aerodynamic characteristics of plasma synthetic jets. The maximum output voltage of the pulse source is 50kV, the maximum frequency is 5kHz, the rising edge is 20ns-30ns, and the half-height width is 50ns. The discharge voltage in the experiment is about 4.7kV, discharge current 20A (Jia Min, Liang Hua, Song Huimin, et al. Aerodynamic excitation characteristics of nanosecond pulsed plasma synthetic jet [J]. High Voltage Technology, 2011,37(6):1493-1498.). The discharge current of this type of power supply is small, which is not conducive to the heating of the cavity of the plasma synthetic jet actuator.
中国科学院电工研究所对多个等离子体合成射流激励器同步放电进行了研究，专利(申请号2015100580904)公开了多个等离子体合成射流激励器同步放电的装置及方法，其装置包括多个高压模块，通过开关同步触发技术对多个等离子体合成射流激励器进行同步激励，使多个激励器同步放电，但是这种装置采用多个高压模块，增加了装置的复杂性。The Institute of Electrical Engineering, Chinese Academy of Sciences has conducted research on the simultaneous discharge of multiple plasma synthetic jet actuators. The patent (application number 2015100580904) discloses a device and method for synchronous discharge of multiple plasma synthetic jet actuators. The device includes multiple high-voltage modules , synchronously excite multiple plasma synthetic jet exciters through switch synchronous trigger technology, so that multiple exciters are discharged synchronously, but this device uses multiple high-voltage modules, which increases the complexity of the device.
综上所述，国内外大多是在研究单个等离子体合成射流激励器的特性，而且使用的电源装置也存在许多缺点。不能使多个等离子体合成射流激励器同步放电，装置结构复杂，结构不紧凑，放电电流小，等离子体合成射流速度低，工作效率低。To sum up, at home and abroad, the characteristics of a single plasma synthetic jet actuator are mostly studied, and the power supply device used also has many shortcomings. Multiple plasma synthetic jet exciters cannot be discharged synchronously, the structure of the device is complex, the structure is not compact, the discharge current is small, the velocity of the plasma synthetic jet is low, and the working efficiency is low.
