Dooro inductor-ka ku habboon ee ku wareejinaya korontada | hel

Inductor , oo sidoo kale loo yaqaano inductor , waxaa lagu gartaa "inertia weyn" ee hadda socda. Si kale haddii loo dhigo, iyada oo ay ugu wacan tahay sii socoshada qulqulka, hadda ku jira inductor waa inuu ahaado mid joogto ah, haddii kale waxay soo saari doontaa koronto weyn. Inductor-ku waa qayb birlab ah, sidaas awgeed waxa ay si dabiici ah u leedahay dhibaatada saturation magnetic. Codsiyada qaarkood waxay ogolaadaan in inductance-ka, codsiyada qaar waxay u oggolaanayaan indha-indheeyeyaal -ka inay ka soo galaan saturation qiimo gaar ah oo hadda jira, codsiyada qaarkood ma oggola inductor-ka in la buuxiyo, taas oo u baahan kala soocida wareegyada gaarka ah.

Inta badan, inductor-ku wuxuu ka shaqeeyaa "gobolka toosan", halkaasoo inductance ay tahay mid joogto ah oo aan isbeddelin korantada terminaalka iyo hadda. Si kastaba ha ahaatee, waxaa jira dhibaato aan la iska indho tiri karin, taas oo ah, dabaysha ee inductor waxay u horseedi doontaa laba qaybood oo qaybsan (ama parasitic parameters), mid waa iska caabbinta dabaysha ee lama huraanka ah, midda kale waa awoodda qallafsan ee la qaybiyey ee la xidhiidha dabaysha. habka iyo agabka.

Awoodda qalloocan waxay leedahay saameyn yar marka la eego soo noqnoqoshada hooseeya, laakiin waxay si tartiib tartiib ah u soo baxdaa kororka soo noqnoqda. Marka inta jeer ee soo noqnoqda uu ka sarreeyo qiimo gaar ah, inductor wuxuu noqon karaa sifo awood leh. Haddii capacitance baadi ah uu "ku urursan yahay" galay capacitor ah, sifooyinka capacitance ka dib inta jeer ee qaar ka mid ah waxaa laga arki karaa wareeg u dhigma ee inductor ah.

Xaaladda shaqada ee induction ee wareegga

Sida capacitor-ku u leeyahay dallaca iyo dareeraha hadda jira, inductor sidoo kale wuxuu leeyahay habka dallacaadda iyo soo-dejinta. Qulqulluun kan capacitor ta’uu danda’a jedhameera. Ilaa inta korantada inductor-ku isbedesho, heerka isbeddelka di/dt sidoo kale wuu isbedeli doonaa; Danabka hore waxa uu ka dhigayaa kor u kaca hadda si toos ah, danab gadaneedkuna waxa uu hoos u dhigaa si toos ah.

Aad bay muhiim u tahay in la xisaabiyo inductance saxda ah si loo doorto inductor ku habboon iyo capacitor-ka wax soo saarka si loo helo qulqulka ugu yar ee wax soo saarka.

Doorashada soo-jiidashada ee hoos-u-dejinta Korontada

Marka la dooranayo inductors ee sahayda beddelka ee buck-ka, waxaa lagama maarmaan ah in la go'aamiyo korantada wax-soo-saarka ugu badan, danabka soo-saarka, inta jeer ee beddelka, qulqulka ugu sarreeya ee hadda iyo wareegga waajibaadka.

Xulashada inductance ee kor u wareejinta Korontada

Xisaabinta inductance-ka ee kor u qaadista sahayda korantada, marka laga reebo in xidhiidhka ka dhexeeya wareegga shaqada iyo korantada inductance uu isbeddelay, habka kale wuxuu la mid yahay kan hoos u dhigista sahayda korantada.

Fadlan ogow in si ka duwan sahayda tamarta buck-ka, culayska hadda korantada ee korantada korantada lagu kordhiyo had iyo jeer ma bixiyo hadda inductor. Marka tubbada shiduhu ay shidantahay, inductor-ku waxa uu ku soo qulqulaa dhulka isaga oo sii maraya tuubada beddelka, halka culayska hadda socdaa uu bixinayo capacitor-ka wax soo saarka, markaa capacitor-ka wax soo saarku waa in uu leeyahay awood weyn oo kaydin tamar ah si uu u bixiyo wakhtiga hadda loo baahan yahay rarka muddadan. Si kastaba ha noqotee, inta lagu jiro daminta daminta, hadda socodka qulqulaya ma aha oo kaliya inuu bixiyo culeyska, laakiin sidoo kale wuxuu dalacayaa capacitor wax soo saarka.

Guud ahaan, marka qiimaha inductance uu weynaado, qulqulka wax soo saarka ayaa yaraan doona, laakiin jawaabta firfircoon ee tamarta korontada ayaa sidoo kale ka sii dari doonta, sidaas darteed xulashada qiimaha inductance waxaa lagu hagaajin karaa iyadoo loo eegayo shuruudaha codsiga gaarka ah ee wareegga si loo gaaro saamaynta ugu fiican.

Kordhinta soo noqnoqda beddelka waxay ka dhigi kartaa inductance yar, si cabbirka jireed ee inductor uu noqdo mid yar oo badbaadiyo booska guddiga wareegga, sidaas darteed sahayda korantada ee hadda jirta waxay leedahay isbeddel ku yimaada soo noqnoqoshada sare, si loo buuxiyo shuruudaha yaryar iyo kuwa yaryar. mugga alaabta elektarooniga ah.

Kor ku xusan waa hordhaca doorashada inductor ku habboon sahayda wareejinta. Haddii aad rabto inaad wax badan ka ogaato inductor-ka, fadlan xor u noqo inaad nala soo xidhiidho.
