Abstract: The paper analyzed principle of voltage space vector pulse width modulation(SVPWM),designed SVPWM frequency conversion speed regulation system which took DSP chip as(controller,)(introduced) hardware structure of the system and its software realization,built up simulation model of the(system) and then did simulation test to the system with Matlab/Simulink (software.) The(simulation) results confirmed that the system had fast starting,small overshoot and small steady-state torque(ripple,) as well as good static and dynamic performance.
