Kusintha kwamagetsi kumatengera ukadaulo wosinthira pafupipafupi kwambiri kuti usinthe mawonekedwe osakhazikika komanso osokonekera (AC) kukhala magetsi otsika mwachindunji (DC) omwe amafunidwa ndi zida zina.M'malo mwake, mphamvu yosinthira imatha kunenedwa kuti ndi chida chothandizira pamtima pazida zina, ndipo zotsatira zake ndizochepa kwambiri.

Lingaliro lachikatikati la kusintha kwa magetsi: kuonjezera mphamvu ya magetsi molingana ndi njira monga kuonjezera mphamvu yotulutsa mphamvu, potero kuchepetsa kukula ndi kulemera kwa ukonde wa chosinthira mphamvu.Ubwino wofunikira pakutembenuka kwamagetsi ndikupititsa patsogolo kusinthika kwamphamvu kwamagetsi amagetsi.Mphamvu yamagetsi yamagetsi ya PC ndi 70% -75%, pomwe mphamvu yamagetsi yofananira ndi 50% yokha.

Kudalirika kwa mphamvu yotulutsa mphamvu kumakhala pakusintha kwa pulse wide, komwe kumatchedwa pulse wide modulation PWM.

Zomwe zimagwira ntchito pamagetsi osinthira ndizosavuta.

Mphamvu yamagetsi yamagetsi ikalowa mumagetsi, kusokoneza kwamagetsi kwakanthawi kochepa komanso kusokoneza kwamagetsi kumachotsedwa koyamba malinga ndi chipangizo chojambulira cha coil ndi capacitor, kenako magetsi okwera kwambiri a DC amapezeka molingana ndi chipangizo chowongolera ndi kusefa.Kenako gawo la kulumikizana kwapang'onopang'ono limasefedwa, kotero kuti mphamvu yamagetsi yamagetsi yamagetsi ya DC ya zida zofananira imatuluka.
