Abstract

This paper discusses the fine modelling and control of three-phase PWM inverter by means of average model method. First, the average model method is used step by step to make it easier to read in the power stage design. The second part is the controller design which has the inner current controller and the outer voltage controller to help controlling accurately. Finally, the linear and nonlinear loads were tested respectively on the basis of fine modelling, being meaningful to do the research of nonlinear loads. The simulation results have shown that the average model method is an effective research solution of three-phase PWM inverters, which can be easily generalized to modelling and control of any other PWM inverters.
