In the present situation of increasingly energy shortage of the world, this article focuses on apply the SVPWM control technology which have little harmonic, high utilization rate of DC voltage etc,to the high efficiency energy-saving features of active inverter.Studying on the three-phase voltage source active inverter in-depth,then the basic principles and control algorithms of SVPWM is researched in detail,building the overall structure of the three-phase active inverter control which based on SVPWM control strategy. the control algorithms is simulated dynamically by using SIMULINK dynamic simulation tool. And then building the simulation model of the three-phase active inverter system which based on PWM (using SVPWM, SPWM) control strategy,and have a comparison between the two control simulation results,proposing the SVPWM should be applied to the inner-feeding cascade speed control system,and the simulation results achieve the desired effect,which promise the SVPWM control technology would have a very broad application prospects. |
