Description

Technical field [0001] The present invention relates to the technical field of high-voltage pulse power supplies, in particular to a negative-polarity high-voltage pulse power supply for synchronous discharge applications of multiple plasma synthesis jet exciters. Background technique [0002] Flow control can be divided into two categories: passive control and active control. Active control is to directly inject appropriate disturbance modes and energy into the flow field to make it interact with the flow in the system to achieve control. The control effect can be based on the actual work. The conditions are adaptively adjusted. As a brand-new active flow control technology, synthetic jet does not require an air supply system. It has the characteristics of simple structure, fast response, working frequency bandwidth and zero mass flow rate, and has a wide range of applications in the field of flow control. With the rapid development of plasma technology, plasma synthetic jet te...
