摘要:在工業(yè)上,交流電機得到廣泛應用,其中相當一部分需要由調速裝置供電。采用了一種較為容易實現、普遍用于變頻器的SPWM調制方案,并結合TMS320LF2407芯片,使系統(tǒng)更容易實現。
關鍵詞:供電; 變頻器;SPWM

Abstract:In the industry,the AC motor has been used widely,and lots of them need the power supply of timing equip.Use a method named SPWM which iS used in transducer wi dely and come to realize easily.and corn.
bined with the chip of TM$320U 407 which makes the system realized easylier.
Key words:power supply;transducer;SPWM
