Izindlela ezahlukene zokuxhuma izintambo zingathinta amandla okusabalalisa ama-windings e-transformer, okuthinta ngqo ukusebenza kwama-transformer. Kulesi sihloko, sizogxila kupharamitha yama-transformer.
I-capacitance esatshalaliswe ye-transformer iyi-capacitance ye-parasitic eyakhiwe ngenxa yokuba khona kokungafani okungenzeka. Iyipharamitha kagesi ekhona kabanzi, lapho kukhona i-capacitance esatshalaliswe phakathi kwama-insulator amabili inqobo nje uma kunomehluko we-voltage. I-capacitance esatshalaliswe ayinawo umthelela omkhulu kumasekethe kuma-frequency aphansi, kodwa imiphumela yayo kumele icatshangelwe kuma-frequency aphezulu.
I-capacitance esabalele yama-windings e-transformer ingahlukaniswa izingxenye ezine eziyinhloko:
(1) amandla okushintsha phakathi kwe-turn. I-capacitor eyakhiwe umehluko ongaba khona phakathi kokujika okuseduze. Nakuba inani le-capacitance phakathi kokujika okukodwa lincane, ukushaja okuphindaphindiwe nokukhipha phakathi kokujika kungaholela ekuwohlokeni kokufakwa kokushisa kanye nokuwohloka ngisho nokujikeleza okufushane kwentambo enamel ezimweni ezinamandla aphezulu noma ezinamandla aphezulu.
(2) Umthamo we-Interlayer. Umthamo phakathi kwezingqimba ezahlukene ekujikeni okufanayo. Umthamo we-Interlayer uwumthombo oyinhloko we-distributed capacitance, eyakha i-oscillation loop ene-leaking inductance kuma-frequency aphezulu, okwenza izinkinga zokuphazamiseka kwe-electromagnetic zande futhi kwandise ukucindezeleka kwe-voltage ku-switching transistor.
3) I-capacitance ehlanganisayo. I-capacitance phakathi kwe-primary kanye ne-secondary, primary kanye ne-VCC, kanye ne-secondary kanye ne-VCC windings. Le capacitance inikeza indlela yokuxhumanisa yokuphazamiseka kwemodi evamile, okungabangela umsindo ovela ohlangothini oluyinhloko ukuthi udluliselwe ohlangothini lwesibili, okuthinta ukuzinza kokukhipha.
(4) Umthamo olahlekile. Umthamo wokugoqana kuya kuma-cores kazibuthe, izendlalelo zokuvikela, noma ama-casing ubangelwa yizici ezifana nesekethe, isakhiwo, noma ukwakheka. Nakuba la ma-capacitor emancane, angaba nomthelela ezicini zemvamisa ephezulu ngaphansi kwezakhiwo ezithile.
I-capacitance esabalele yama-windings e-transformer ivame ukuba yingozi, futhi umthelela wayo kumasekethe ungokulandelayo:
1. Izinkinga zokuhambisana kwe-electromagnetic. I-capacitance esatshalaliswayo inikeza indlela yokuxhumanisa phakathi kwe-primary kanye ne-secondary windings, okubangela umsindo ohlangothini oluyinhloko ukuze uxhumeke ohlangothini lwesibili ngokusebenzisa i-capacitance, okwenza ukuphazamiseka kwemodi evamile futhi kulimaze ubuqotho besignali yesekethe.
2. Ukwehla kokusebenza kahle. Ama-capacitor asakazwayo kumasekethe angakha ama-capacitive currents, okuholela ekwandeni kwamandla asabelayo ama-transformer kanye nokwehla kokusebenza kahle okuphelele. Okwesibili, inqubo yokushaja nokukhipha amandla okusabalalisa yandisa ukulahlekelwa okwengeziwe, ukushisa okugoqekayo kuyanda, kanye nokusebenza kahle kuyancipha.
3. Umonakalo wokufakwa komoya. Amandla okusebenza asakazekile angabangela ukugcwala kwensimu kagesi yendawo ezimweni ze-voltage ephezulu, okuholela ekwandeni kokuvuza kwamandla kagesi kanye nokuwohloka kwezinto zokufakwa komoya.
4. Ukwehla kokuzinza kokusebenza. Amandla okusebenza asakazekile kanye nokungena kokuvuza kwakha isekethe ezwakalayo, okubangela ukujiya kwamandla kagesi ekunikezeni amandla okushintsha, okuholela ekucindezelekeni kwamandla kagesi ngokweqile ku-transistor eshintshayo kanye nomonakalo kudivayisi.
Ezisetshenzisweni zemvamisa ephezulu, i-capacitance esabalalisiwe ingashintsha imodeli yesekethe efanayo yama-transformer, okubangela impendulo yemvamisa ukuba iphambuke enanini lomklamo futhi ithinte ukuzinza kwesekethe. I-capacitance esabalalisiwe ingadlulisela nomsindo wokushintsha ku-terminal yokukhipha ngokuxhuma, ukwandisa i-power ripple kanye nokunciphisa ikhwalithi yokukhipha.
5. Ukulinganiselwa kokuklama kanye nezindleko ezikhuphukile. Ukuze kuncishiswe ithonya le-capacitance esabalalisiwe, kungadingeka ukuklama amasekethe e-RC buffer compensation engeziwe, okwandisa ubunzima kanye nezindleko zomklamo wesekethe. Ezimweni ezivame kakhulu, ukuze kuncishiswe i-capacitance esabalalisiwe, kungadingeka ukusebenzisa izinto zokushisa ezibizayo kanye nezinqubo eziyinkimbinkimbi ukuklama ama-transformer, ngaleyo ndlela kwandiswe izindleko.
Kuma-transformer anemvamisa ephezulu, singanciphisa amandla asakazwayo e-transformer ngokwandisa ibanga phakathi kwama-windings, ukwandisa ukujiya kokushisa, sisebenzisa izinto zokushisa ezihlala njalo ze-dielectric eziphansi, ukuthuthukisa izindlela zokushisa, kanye nokwandisa ukwakheka kwezingqimba zokuvikela.
