Kufotokozera Kwachidule:

Zoyambira zofewa (zoyambira zofewa) ndi gulu la zoyambira zofewa ndi zoyimitsa zofewa, zoteteza zatsopano mu imodzi mwa zida zowongolera mota. Gawo lake lalikulu limalumikizidwa ku magetsi okhala ndi thyristor yozungulira yofanana ndi galimoto komanso dera lake lowongolera zamagetsi. Imatha kugwiritsa ntchito njira zosiyanasiyana, kuwongolera ngodya yoyendetsera thyristor yotsutsana kuti isinthe magetsi olowera a mota molingana ndi zofunikira zosiyanasiyana ndikukwaniritsa ntchito zosiyanasiyana. Zoyambira zofewa ndi zosinthira ma frequency ndi ntchito ziwiri zosiyana kwambiri za zinthu. Chosinthira ma frequency chimagwiritsidwa ntchito m'malo omwe amafunikira liwiro, kutulutsa sikungosintha magetsi okha komanso kusintha ma frequency nthawi imodzi. Choyambira chofewa kwenikweni ndi chowongolera ma voltage poyambira mota, ma frequency a voltage otuluka sasintha. Chosinthira chimapereka ntchito yonse yoyambira yofewa, koma ndi yokwera mtengo kwambiri kuposa choyambira chofewa, kapangidwe kake ndi kovuta kwambiri. Choyambira chofewa cha mota chimagwiritsa ntchito ulusi pakati pa magetsi ndi choyambira chofewa cha mota chowongolera, chowongolera ngodya ya thyristor conduction, voteji yolowera ya mota imakwera kuchoka pa zero kupita ku ntchito yokonzedweratu pang'onopang'ono, mpaka kumapeto kwa kuyambitsa, zomwe zimapangitsa kuti voteji ya mota, yomwe ndi yoyambira pang'onopang'ono, panthawi yoyambira pang'onopang'ono, mphamvu yoyambira ya mota imawonjezeka pang'onopang'ono.
