【Abstract】 The basic principle of space-vector PWM for three-level inverter is analyzed,and a novel algorithm for SVPWM based on multiple-NN is proposed.The calculation time is shortened,and the converter switching frequency is increased by using the fast parallel computation and learning capability of NN.A computer simulation model of space-vector PWM controller for three-level inverter is developed in Matlab/Simulink together with the NN toolbox. The simulation results show the feasibility and effectiveness of multiple-NN-SVPWM.更多还原
