A korontada transformerless: Ujeeddada, gaar ahaan, mabda'a hawlgalka ee hay'adaha

sahay Power for kombiyuutarada shakhsi ku salaysan yihiin wareeggeedii transformerless ku xiran shabakadda (dhab ahaantii, waxa ay korontada pulsed). Waxay waxaa lagu gartaa qiimaha sare ee hufnaan, cabbir yar iyo miisaanka yar yahay. Si kastaba ha ahaatee, korontada transformerless uu leeyahay a khasaare weyn - Sabuul qaylada in ay leeyihiin saamayn taban ku leh kumbiyuutarada kale nidaamyada iyo qalabka kale ee macaamiisha qalabka korontada. Sidaa darteed, wax soo saarka kasta oo ag maraaba sida imtixaanka weyn ee waafaqsan electromagnetic qalab kale. Waxaa intaas dheer, qaybta korontada transformer yar ayaa go'doomin korontada ee qayb ka mid ah circuit koronto ka danab ku dhaxe. Tani, ka bacdi, waxay u baahan tahay isticmaalka tallaabooyin ammaanka gaar ah inta lagu guda jiro dib u samaynta of articles sida.

Transformerless korontada, meelaha ugu weyn ee functional

qalab ka kooban yahay qaybaha soo socda:

- rectifier shabakad;

- filter EMC;

- circuit farganka,

- filter capacitive;

- Converter danab ku salaysan inverter awood garaaca wadnaha,

- circuit guud danab wax soo saarka ah,

- circuit gacanta;

- sameynta iyo gudbinta circuit of calaamadaha-celin si wareeg gacanta.

xubno dheeraad ah

Iyadoo ku xiran ee model iyo ka shaqeynayaan, korontada transformer yar ka mid noqon kara wareeggeedii dheeraad ah sida jaangooyaha toosan qaab Discrete ama isku dhafan, talooyin ilaalinta dollar oo danab wax soo saarka iyo hadda, iyo sidoo kale circuit xakamaynta. Intaas waxaa sii dheer, in korontada sida mid noqon kara circuitry u dhalin karo calaamadaha gacanta ee gaarka ah in ay bixiyaan ku habboon ee qalabka si circuit feed a.

Mabda 'hawlgalka

Mase Koronto guud raanta danab DC waxaa la sameeyaa danab aqbasho xaafuun. First, waa la hagaajin iyo smoothed. Natiijadu waxay tahay danab DC ah, ka dib markii taas la aasaasay of digir qaab heer ah tobanaan kilohertz. Intaas ka dib, digir waxaa loo bedelay inay dhanka sare leh Wehliyaha u dhigma, oo mar kale u kacaysaa sixitaan iyo yeeesha. sayidkiisa Guntin The converters danab korontada transformerless yihiin muhiimka ah, iyo gaar ahaan qeybta awood ay (stage saarka-awood sare). Marxaladaha Kuwani waxa loo qaybin karaa hal-ku dhamaaday iyo-riix jiido.

Koronto hagaajin karo

Si ay ula qabsadaan qiyamka danab wax soo saarka ee qalabka transformerless inta badan farsamo ee loo isticmaalo isbedbeddelka width garaaca wadnaha, taas oo ah isbedelka ku dhacay muddo atar, iyo Derewalku therebetween. Marka ay tani inta jeer Isbadal isma badelin. Xiriirka ka dhexeeya tiro kuwaas oo sida muddada garaaca wadnaha iyo hakinta, waxay ku xiran tahay danab wax soo saarka. Waxaa si toos ah u beddelay si ay u ilaaliyaan danab saarka gudahood qiimaha magacaaban ah.
