The conventional multilevel space vector modulation(SVM) method is more complex because of the calculations for selecting various vectors,which makes the algorithm more difficult to be implemented when the number of cascaded power units is larger.

Design and Implementation Using dSPACE of SVPWM Based on ANN;

On the basis of the principle of space vector pulse width modulation,introducing the formation of SVPWM in the cartesian coordinate system,experimenting on the actual inverter platform,and the implemention of SVPWM and results are given on TMS320LF2407A.

In today s AC servo system,the vector control theory and SVPWM technique make the AC motor can achieve the performance as good as DC motor.

Space vector pulse width modulation (SVPWM) method of a three-level neutral-point-clamped (NPC) inverter is studied comprehensively in this dissertation.

On the basis of this,a hardware driving system of PMSM whose core is MC56F8323 was designed, and a detailed explanations to space voltage vector pulse width modulation (SVPWM) method is given and its design method of PI controller, the software implementation method was given.

Fixed active power and coordinate ac voltage and frequency control scheme are put forward in sea converter while the fixed dc voltage control and fixed reactive power control scheme are applied in land converter, which aims at realizing independent control of P, Q flow and enlarge the speed range of DFIG with the help of SVPWM.

To provide the necessary design parameters for the actual motor control system,the simulation moled of vector control system based on space vector pulse width modulation(SVPWM) for Asychronous Motor is established in MATLAB/Simulink,according to the principle of SVPWM and the theory of vector control system.
