| Abstract: | The principle of SVPWM for the three -phase voltage source inverter is described. The SVPWM conventional algorithm and the SVPWM fast algorithm which can be easily implemented on the microprocessor are presented. The equivalence and validity of two algorithms are verified by means of theoretical analysis and simulation study. In particular, it is not necessary to identify the sector to which the voltage reference signal belongs using the SVPWM fast algorithm, so that its executing speed is faster and it is more practical compared with the SVPWM conventional algorithm. |
