Application of Zero-vector Control to Three-phase Inverter
In this paper,a new application of three-phase inverter using zero-vector control is proposed.In order to control the amplitude of output current,the d-q axis coordinate transformation,hysteresis controller and space vector strategy are adopted.Besides,the frequency of output current also can be adjusted by zero-vector control.Therefore,the proposed inverter has lower switching loss,higher system efficiency and better dynamic response.Use VisSim simulation software and TI TMS320F28335 chip to implement the proposed control strategy.The controller has several advantages such as easier to control,smaller circuit size and fully digital design etc.Finally,the experimental results are compared with the proposed theory for verifications.
