I-Complexity: Ibhuloho leRexifier Rectifier liyinkimbinkimbi kakhulu kune-Half-wave rectifier elula ngoba idinga ama-diode amane esikhundleni esisodwa.Lokhu kungangezelela ubunzima bomklamo wokujikeleza kanye nomhlangano.

Ukulahleka kwamandla: Ukwehla kwamandla kagesi kuwo wonke ama-diodes kuhumushela ekulahlekelweni kwamandla, okungabaluleka ezisekelweni eziphezulu zamanje.Lokhu kunciphisa ukusebenza kahle kwamandla kagesi.

Isizukulwane sokushisa: Ukulahleka kwamandla ema-diode kuholela ekushiseni kokushisa, okungadinga izinyathelo ezingeziwe zokupholisa ezifana nokushisa okufana nokushisa okushisayo ukuvikela ukushisa ngokweqile, ikakhulukazi kuzinhlelo zokusebenza eziphezulu.

4. Kwenzekani uma ubeka i-DC ungene ebhulohweni le-Bridge?

Akunasisekelo: I-Bridge eyindalo yakhelwe ukuguqula i-AC ku-DC ngokuvumela okwamanje ukuthi idlule ema-diodes endaweni eyodwa.Uma usebenzisa i-DC kokufaka, ama-diode ngeke ashintshe noma alungise okwamanje kusukela i-DC isivele ingenamikhawulo.

Ukwehla kwamandla kagesiLokhu kusho ukuthi ukuphuma kwe-DC voltage kuzokwengeza kancane kune-VC Voltage yokufaka.

Isizukulwane Sokushisa: Ukudlula kwamanje ngokusebenzisa ama-diode azokhiqiza ukushisa ngenxa yokuqedwa kwamandla (P = I²R).Lokhu kushisa kungakubaluleka uma okufakwayo okuphezulu kuphezulu, okungenzeka kulimaze ama-diodes noma afune izindlela zokushisa zokushisa.

Okubi kakhulu: Uma i-voltage esetshenzisiwe ye-DC iphakeme kakhulu kunamandla kagesi we-didediIzilinganiso ezifanele zikagesi kufanele zilandelwe ukugwema ukulimala.
