Description

technical field [0001] 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 the synchronous discharge application of multiple plasma synthetic jet actuators. Background technique [0002] 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 adva...
