| Abstract: | A novel fast algorithm of SVPWM which is easily joined with vector control algorithm is proposed. The matrix equation of operation time of each space vector responding to voltage components in the two-phase rectangle coordinates is derived. SVPWM can be implemented with simple arithmetic operation, thus the calculation of circular function is avoided. The experimental results prove that the fast algorithm is valid and available. |
