| Abstract: | Describes the four ways producting SPWM wave which are often used in VVVF system and studies the calcutating formulas for various SPWM on/off switch points and their deduction. By using these formulas,we have calculated a series of on/off switch points data and presented 4 new way of analyzing different normonics of SPWM wave with these data. The results of harmoniC analysis proved that natural sampling is better than other methods. |
