變頻調速器定義

    變頻調速器

    變頻調速器是把工頻電源(50Hz或60Hz)變bian換huan成cheng各ge種zhong頻pin率lv的de交jiao流liu電dian源yuan

，以yi實shi現xian電dian機ji的de變bian速su運yun行xing的de設she備bei，其qi中zhong控kong製zhi電dian路lu完wan成cheng對dui主zhu電dian路lu的de控kong製zhi，整zheng流liu電dian路lu將jiang交jiao流liu電dian變bian換huan成cheng直zhi流liu電dian，直zhi流liu中zhong間jian電dian路lu對dui整zheng流liu電dian路lu的de輸shu出chu進jin行xing平ping滑hua濾lv波bo
，逆ni變bian電dian路lu將jiang直zhi流liu電dian再zai逆ni成cheng交jiao流liu電dian。
