Ọkara-efegharị efegharị rectifier, ya na-arụ ọrụ ụkpụrụ na circuit

Power electronic na sekit na sekit dị iche iche na nzube-achọ a DC voltaji isi iyi. Na ot netwọk nwetụ ugbu a, ya ugboro bụ na ọtụtụ ikpe 50 Hz. Udi mgbanwe site na voltaji uru bụ a sinusoid na a oge nke 0,02 sekọnd, na otu ọkara ka na-anọpụ iche na ọ dị mma, nke abụọ - na-ezighị ezi. Iji dozie nsogbu nke ya mgbanwe n'ime a mgbe nile na-etinyere AC rectifiers. Ha na-abịa dị iche iche na aghụghọ na atụmatụ nwere ike iche na.

Iji ghọta otú ihe ndị kasị dị mfe ọkara-efegharị efegharị rectifier, otu ga-akpa ịghọta ọdịdị nke eletriki conductivity. Ugbu na-eduzi ije nke ebubo ahụ nke nwere ike nwere ihe-abụghị polarity, conventionally ha na-ekewa n'ime electrons na oghere, ma ọ bụ - donors na acceptors enwe conductivity «n» na «p» ụdị, karị. Ọ bụrụ na ihe si n-conductivity jikọọ na ọzọ, p-ụdị, na ha interface a na-akpọ pn-nkwụsị bounding ije nke ebubo ahụ na one direction. Nke a chọpụtara ekwe ojiji nke okporo ọkụ technology, dochie ya kasị tube ngwá electronic.

Ọkara-efegharị efegharị rectifier isi mejupụtara a diode ngwaọrụ a pn nkwụsị. The nwetụ voltaji nyere ndenye circuit, na mmepụta nwere naanị ọkara ya, onye na-kwekọrọ na direction ịmafe rectifier diode. The akụkụ nke abụọ nke oge, na-enwe ndị na-abụghị direction, anaghị agafe ma na "ebipụ."

The esereese egosi a otu-adọ rectifier na a na-eji ọtụtụ n'ime ndị nkịtị home na ngwaọrụ na-zubere maka anụ ụlọ iji. Ke ulo oru gburugburu ebe obibi na-eji atọ-adọ netwọk, na Ya mere AC ka DC Ntụgharị circuit nwere ike mgbagwoju anya. Ọzọkwa, dị ka a na-achị, na-agụnye a yinye fuuz na nzacha. Na circuit input nwere ike tụgharịa ala transformer ma ọ bụ ndị ọzọ AC isi iyi. Rectifier diodes dị iche na ha kwa, isi n'etiti nke dị ugbu a bara uru na nke diode e mere.

Ọkara-efegharị efegharị rectifier nwere ịrịba mwepu na tụnyere na-na-efegharị efegharị. The voltaji mgbe rectification bụghị n'ụzọ nkịtị na-aga n'ihu, ọ pulsates si a kacha uru efu site polusinusovidnoy eserese ụdị nwere n'etiti pulses efu. Dị otú ahụ mkpumkpu eruba ejikari ụgwọ atụrụ maka site gụnyere a smoothing capacitor pụtara nnukwu quantities (mgbe ụfọdụ tụrụ na ọtụtụ puku microfarads) gbakọọ maka a voltaji erughị n'akparamagwa na circuit mmepụta, dị ka a na-achị, na a oke. Nke a na ezu ana achi achi zuru okè flatness ndịna, kama ịdị ukwuu nke deviations si setpoint na-budata belata, nke na-eme ka o kwe omume na-eme a ọkara-efegharị efegharị rectifier maka powering mfe na sekit na sekit mîkoyomke elu voltaji kwụsie ike.

Na ihe mgbagwoju ikpe, mee zuru-efegharị efegharị idozi circuit sochiri stabilization.
