Research On Driving Power Supply For Synthetic Jet Actuator And Characteristic Of Cymbal Style Pizoelectric Composite Material

Utilizing the disturbance of micro-flow to realize the control on the main flow is an important method of flow control, especially for adaptive wing boundary layer control. Synthetic jet control becomes one of the highest potential methods for flow control, because its actuator has a simple structure and easily to be controlled and less power consume. In general, the synthetic jet is generated through the vibration of the membrane of the actuator driven by piezoelectric materials. In order to realize the adaptive control of micro-flow, the piezoelectric materials must be driven by a signal with high voltage, adjustable frequencies and less harmonic. To integrate into the structure or wing of aircraft, the traditional power supply or signal generator have to be instead by the new signal generation system, because of their weight and power consume and something else.This paper focuses on an integrated single phase, full-bridge voltage inverter that uses the standard DC power supply to output an adjustable frequencies signal to drive the micro-flow actuator. In addition, in this paper the elementary analysis of dynamic response for the piezoelectric ceramic-metal composite materiel structure of Cymbal style have been finished, and the results of simulation of this model were obtained by using ANSYS system.
