Ukulungisa umba wamandla asezantsi kwiziko eliphantsi kwamanzi, ilizwe lam lidla ngokuqesha imbuyekezo yecapacitive, idla ngokusetyenziswa kwicala eliphezulu{0}}levoltage. Nangona kunjalo, -imbuyekezo yecala levoltage ephezulu iyasilela ukusombulula{3}}isigaba sokungalingani. Ngaphaya koko, njengoko i-inductive reactance ye-short{5}}yenethiwekhi yenza ngaphezulu kwe-70% ye-reactance iyonke yenkqubo, imbuyekezo ephezulu{7}}yevoltage ayinciphisi ngokufanelekileyo{8}}ukusabela kothungelwano okanye iphucule indlela emfutshane{9}}yamandla enethiwekhi; kwaye ayiphumeleli injongo yokunyusa imveliso ye-transformer{10}}izibonelelo zayo zithintelwe ubukhulu becala kwizinto eziluncedo zobonelelo lwamandla.
Ngenxa yoko, ezinye izibonelelo ziye zamkela indlela -yembuyekezo embaxa-mbili{1}}ukusebenzisa imbuyekezo yamandla asebenzayo kuwo omabini amanqanaba aphezulu{2}} nasezantsi{3}}evoltage{4}}yeziko elitsha ukusombulula le miba. Imbuyekezo kwisiphelo sothungelwano - esifutshane siphucula kakhulu amandla kunye nokunciphisa ukusetyenziswa kwamandla. Ukusetyenziswa{8}}kwisayithi yembuyekezo yamandla asebenzayo ukujongana nokusetyenziswa kwamandla asebenzayo kunye nokungalingani kwesigaba kwisiguquli somlilo esisezantsi{9}}sombane omfutshane{10}}uthungelwano{11}}ngelixa kwangaxeshanye ukonyusa amandla{12}sisicombululo esithembeke ngokobuchule nesivuthiweyo{13 sisisombululo esinexabiso elincomekayo{13} Xa kuthelekiswa{15}}nembuyekezo yevoltage ephezulu, kwisayithi{16}}imbuyekezo yamandla asebenzayo kwicala eliphantsi{17}}icala levoltage libonelela ngamancedo angenakuthelekiswa nanto ekuphuculeni imeko yamandla, ukuthomalalisa ukuhambelana, ukwandisa imveliso, kunye nokunciphisa ukusetyenziswa kwamandla. Nangona kunjalo, le ndlela ibandakanya iindleko eziphezulu kunye nezixhobo zokusebenza kwiindawo zokusebenza ezinzima, zinciphisa kakhulu ubomi bayo benkonzo. Ukongeza, i-low{20}}i-voltage emfutshane{21}}imbuyekezo yenethiwekhi inokunyusa amanqanaba e-harmonic, ifuna imilinganiselo yokucinezela i-3rd{23}} ukuya kweyesi-7{25}i-harmonics ye-oda; oku kuqhuba utyalo-mali lokuqala, kwandiswe ixesha lokubuyisela, kwaye kukhokelela kwiindleko eziphezulu eziqhubekayo zokugcinwa kunye nokusebenza kakubi kwezoqoqosho ngokubanzi. Ke ngoko, le ndlela ifanelekile kuphela kwiziko elisandula ukwakhiwa.
