【Abstract】 This article proposed a kind of production methodbased on the CPLD multichannel SPWM profile, Described SP-WM wave production mechanism and hardware architecture ofthe experimented system, detailly. The result of the test showedthis method is truly feasible, the output of SPWM waveform isperfect, approached the sine wave, urged the system normally,operated reliably and steadily.更多还原
