Ukunikezwa kwamandla okucwanga

Ukubuka konke komkhiqizo: I-cyclical polarity-reversal (i-bipolar) Ukunikezwa kwamandla okulungisa umqhubi kuyindawo ekhethekile yokuhlinzeka kwamandla we-DC ekwazi ukuzenzakalela noma ngokushintsha ngesandla ukukhipha amandla we-DC ngesikhathi sokusebenza. Umsebenzi wayo oyinhloko ukushintsha ngokuzenzakalela i-polarity ye-terminal yokukhipha-ehle futhi ephambene- ngokuya ngomjikelezo wesikhathi noma wokulawula umyalo, ngaleyo ndlela ukufaka umthwalo (njengomsebenzi wokusebenza ethangini le-electroplating) ezimweni ze-anodic kanye ne-cathodic. Lokhu kuhlinzekwa kwamandla kuhloselwe ikakhulukazi izinqubo ze-electroplating ezinezidingo eziqinile zokugqoka ubuningi, ukunamathela, kanye nokufana. Ezinqubweni ezifana ne-cyclic chromium plating yamanje, ukwanda kwe-electro, ukwanda kwe-alkaline womgqomo wethusi, nokuhlupha, Ukushintshana ngezikhathi ezithile i-polarity kungathuthuka ngempumelelo…

Ukubuka konke komkhiqizo: Ukuhlinzekwa kwamandla okushintsha imvamisa ephezulu kwe-IGBT kuyivayisi yokuhlinzeka kwamandla kwe-DC yesizukulwane esilandelayo esebenzisa i-insulate d-gate bipolar transistor (IGBT) njengengxenye yayo yamandla eyinhloko futhi isuselwa kubuchwepheshe obukhulu be-PWM pulse-width modulation. Umgomo oyisisekelo wokusebenza imi kanje: Amandla wezigaba ezintathu e-AC alungiswa futhi ahlangiswe ukukhiqiza amandla ama-DC abushelelezi, okube eseguqulwa kube yi-AC-frequency ephezulu (imvamisa i-10 kHz kuya ku-50 kHz) yi-IGBT egcwele ibhuloho. Ngemuva kokunyuswa phezulu noma phansi nokuhlukaniswa yi-transformer enemvamisa ephezulu, okukhiphayo ekugcineni kulungiswa futhi kuhlungwe ukuhlinzeka nge-DC voltage ezinzile noma yamanje. Uma kuqhathaniswa nezimpahla zamandla zendabuko ezilawulwa yi-thyristor, Ukunikezwa kwamandla okushintsha imvamisa ephezulu kwe-IGBT kwandisa imvamisa yokusebenza kusuka kumvamisa womugqa.
