Unikezelo lwamandla e-DC ngamacandelo ayimfuneko kwizixhobo ezahlukeneyo zombane kunye neenkqubo, ezibonelela ngomthombo ozinzileyo nothembekileyo wamandla. Nangona kunjalo, kukho iimeko apho i-polarity yobonelelo lombane lwe-DC kufuneka iguqulwe ukuze ihlangabezane neemfuno ezithile. Kweli nqaku, siza kuphonononga ingcamango yokubuyisela umva i-polarity yobonelelo lwamandla e-DC kunye neendlela zokuphumeza oku.
Ukuqonda iPolarity kwi-DC Power Supply
Kunikezelo lwamandla e-DC, i-polarity ibhekisa kwiitheminali ezilungileyo nezingalunganga zombane ophumayo. I-terminal e-positive idla ngokuchazwa njengo-(+), ngelixa i-terminal ethabathayo ichazwa njengo-(-). I-polarity yobonelelo lwamandla ibalulekile njengoko imisela isalathiso sokuhamba kwangoku kwisekethe. Kwizicelo ezininzi, ezifana nezixhobo zombane kunye nezixhobo zoshishino, kubalulekile ukuqinisekisa ukuba i-polarity yokunikezelwa kwamandla ihambelana neemfuno zamacandelo adibeneyo.
Ukubuyisela umva iPolarity kwi-DC Power Supply
Kukho iindlela ezininzi zokubuyisela umva i-polarity yonikezelo lombane lwe-DC, ngokuxhomekeke kwiimfuno ezithile zesicelo. Enye indlela eqhelekileyo kukusebenzisa iswitshi yokubuyisela umva i-polarity okanye i-relay. Le ndlela ibandakanya ukubandakanya ukutshintshwa okanye ukulayishwa kwisekethe enokutshintsha uxhulumaniso lwee-terminals ezintle kunye nezibi, ngokufanelekileyo ukuguqula i-polarity ye-voltage output.
Enye indlela ibandakanya ukusebenzisa imodyuli ezinikeleyo yokubuyisela umva polarity. Ezi modyuli ziyilelwe ukubuyisela umva i-polarity yonikezelo lwamandla lwe-DC kwaye zihlala zisetyenziswa kwizicelo apho ukuguqulwa kwe-polarity kufuneka kwenziwe ngokuguquguqukayo okanye ukude. Banikezela ngesisombululo esifanelekileyo nesithembekileyo sokuguqula i-polarity ngaphandle kwesidingo sokungenelela ngesandla.
Kwezinye iimeko, apho i-polarity ezinikeleyo yokubuyisela umva iswitshi okanye imodyuli ingafumanekiyo, kunokwenzeka ukuphumeza ukuguqulwa kwe-polarity ngokutshintsha ngesandla udibaniso lweetheminali ezilungileyo nezingalunganga zobonelelo lwamandla. Nangona kunjalo, le ndlela idinga ukuqaphela kwaye kufuneka yenziwe kuphela ngabantu abanokuqonda kakuhle kweesekethe zombane ukuze bagweme umonakalo onokuthi ube nombane okanye izixhobo ezixhunyiwe.
Ukubaluleka kokuBuyiswa kwePolarity kwi-DC Power Supply
Ukukwazi ukubuyisela umva i-polarity yobonelelo lombane lwe-DC lubalulekile kwizicelo ezahlukeneyo. Ngokomzekelo, kwiinkqubo zokulawula iimoto, ukubuyisela umva i-polarity yobonelelo lwamandla kunokutshintsha indlela yokujikeleza kwemoto. Ngokufanayo, kwiisekethe ze-elektroniki, amacandelo athile anokufuna i-polarity ethile ukuba isebenze ngokuchanekileyo, kwaye ukukwazi ukuguqula i-polarity yonikezelo lwamandla kuqinisekisa ukuhambelana kunye namacandelo anjalo.
Ngaphaya koko, kuvavanyo kunye neemeko zokusombulula ingxaki, ukukwazi ukubuyisela umva i-polarity yobonelelo lwamandla kunokuba luncedo kakhulu. Ivumela iinjineli kunye neengcali ukuba ziqinisekise ukuziphatha kunye nokusebenza kwezixhobo phantsi kweemeko ezahlukeneyo ze-polarity, zinceda ekuxilongweni kwemiba enokwenzeka kunye nokuqinisekisa ukusebenza ngokufanelekileyo kwezixhobo.
Ukuqukumbela, ukukwazi ukubuyisela umva i-polarity yobonelelo lwamandla e-DC luphawu oluxabisekileyo olufumana ukusetyenziswa kwiinkqubo ezahlukeneyo zombane kunye nezombane. Nokuba yeyokulungiselela iimfuno zecandelo elithile, ukwenza ulawulo oluguquguqukayo, okanye ukuququzelela uvavanyo kunye nokusombulula ingxaki, iindlela zokubuyisela umva ipolarity yobonelelo lwamandla eDC zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kunye nokuhambelana kwezixhobo eziqhagamshelweyo. Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yezisombululo zombane eziguquguqukayo neziguquguqukayo, kubandakanywa amandla okubuyisela umva we-polarity, kulindeleke ukuba ikhule, iqhubele phambili ulutsha kule ndawo.
