SVPWM Technology of Switch Mode Determined by Hardware Based on DSP

The paper introduced fundamental principle of SVPWM technology,and gave a SVPWM control method of switching mode of switch determined by hardware based on TMS320F2407A DSP and its software design. Experimental result showed that switch mode determined by hardware could reduce work load of software of microprocessor in induction motor control system, reduce frequency of power switch, and cut down wastage of switch.
