Ukunikezwa kwamandla okushintsha kuhle.
Ukushintsha ukunikezwa kwamandla kunezinzuzo ezintathu, njengokulandelayo:
I-1) Ukusetshenziswa kwamandla okuphansi nokusebenza kahle okuphezulu.Kusekhethi yokunikeza amandla okushintsha, ngaphansi kwesasasa lesiginali ye-excitation, i-transistor V isebenza ngokushintshana ezimeni zokuvala nokuvala ukucima.Ijubane lokuguqulwa lishesha kakhulu, futhi imvamisa ngokuvamile icishe ibe ngu-50kHz.Kwamanye amazwe anobuchwepheshe obuphambili, amakhulu noma cishe u-1000kHz angafinyelelwa.Lokhu kwenza ukusetshenziswa kwamandla okushintsha i-transistor V kube kuncane kakhulu, futhi ukusebenza kahle kokunikezwa kwamandla kungathuthukiswa kakhulu, okungafinyelela ku-80%.
2) Usayizi omncane nesisindo esincane.Kusukela kumdwebo wohlelo lokushintshwa kwamandla kagesi, kungabonakala ngokucacile ukuthi asikho isiguquli esindayo samandla esisetshenziswa lapha.Njengoba amandla ahlakaziwe ku-tube V yokulungisa ancipha kakhulu, isinki esikhulu sokushisa sibuye sishiywe.Ngenxa yalezi zizathu ezimbili, ukunikezwa kwamandla okushintshwa kuncane ngosayizi futhi kulula ngesisindo.
3) Uhla olubanzi lokuqiniswa kwamandla kagesi.I-voltage ephumayo ye-switch switching power supply ilawulwa umjikelezo womsebenzi wesignali evusa amadlingozi, futhi ukuguqulwa kwe-voltage yesiginali yokufaka kunganxeshezelwa ngokushintshwa kwemvamisa noma ukuguquguquka kobubanzi.Ngale ndlela, lapho i-voltage yegridi yamandla ishintsha kakhulu, isengaqinisekisa i-voltage ephumayo ezinzile.Ngakho-ke, uhla lokuzinza kwe-voltage lokushintshwa kwamandla lubanzi kakhulu futhi umphumela wokuzinzisa kagesi muhle kakhulu.Ngaphezu kwalokho, kunezindlela ezimbili zokushintsha umjikelezo womsebenzi: ukuguquguquka kobubanzi be-pulse kanye nokuguqulwa kwemvamisa.Ukushintshwa kwamandla kagesi akugcini nje ngokuba nezinzuzo zobubanzi be-voltage stabilization, kodwa futhi kunezindlela eziningi zokubona ukuzinza kwe-voltage.Abaklami bangakwazi ukukhetha ngokuguquguqukayo izinhlobo ezihlukahlukene zokushintshwa kwamandla ngokuya ngezidingo zezinhlelo zokusebenza ezingokoqobo.
Ngethemba ukuthi ingakusiza.
