I rectifier esigcwele igagasi, nendlela okusebenza

Rectifier ngokuthi amandla kagesi converters, okuyizinto Semiconductor noma enye idivayisi elekthronikhi yokuguqula amandla okokufaka AC ukuze DC okukhiphayo. Wave rectifier eyakhelwe nengxenye-ibhuloho noma ibhuloho wesifunda, ukwakheka eningiliziwe esizokucabangela.

Ingqikithi yalo kudivayisi kanye rectifier esigcwele wave

Eziningi zalezi amadivaysi kudala unidirectional yezwakala voltage. Ukuze bushelelezi okusizwa ukushaya, sebenzisa izihlungi ekhethekile.
Ukuze uthuthukise imingcele rectifier kudingekile ukunikeza ukugeleza zamanje kokubili isigamu-izinkathi voltage input. Ngenxa yale njongo, izinhlobo ezimbili izifunda esetshenziswa a ukulungiswa kwananoma isigamu-wave, okuyinto ukusebenza njengoba antiphase futhi synchronism nge umthwalo ezivamile.

Nale ukufakwa zidinga ezimbili umthombo voltage eyinhloko, okuzodingeka iphuzu ovamile. Leli cebo ibizwa ngokuthi "esigcwele wave rectifier nge iphuzu phakathi nendawo." Inani isilinganiso voltage ku resistors umthwalo at ukulungisa esigcwele wave izinkomba ezinjalo ngeke idlule kabili circuit isigamu-wave.

Kufanele kuqashelwe ukuthi dvuhpolupeiodnoy izikimu banezimfanelo midpoint, sinezici yako emibi. Lapho zamanje uphasisa diode esisodwa okuphambene reverse voltage isiqongo isigaba ifinyelela esiphezulu voltage okokufaka kabili, yini okufanele zikhunjulwe ngokukhetha diodes ngokuba rectifier.

Kule ndaba, cabangela olunemininingwane ethe xaxa esigcwele wave rectifier wesifunda kokuba okuqukethwe metal kokuba asebenzayo okulingana elikhulu ukumelana kwangaphakathi. Lokhu kuholela khona ukulahlekelwa enkulu ehlotshaniswa ne-Ukushisa abalulekile transformer.

Ngo bakha wesifunda enjalo kokuba capacitor bushelelezi, kubalulekile ukuba sicabangele ukuthi voltage nesilinganiso kushintshana uhlale e amagugu yokusebenza, okuyizinto kakhulu ezincane kuno amplitude esiphezulu. In the ukungabikho umthwalo phezu capacitor voltage kuyalungiswa uhlale amplitude alinganayo. Lokhu kusho ukuthi rectifier esigcwele wave kokuba owodwa esigabeni kushintshana samanje capacitor 12, lapho kungekho umthwalo ithola voltage ka 17 V. Kule, singaphetha ngokuthi ngaphansi komthwalo voltage kuyalungiswa incipha, kodwa akubi esingaphansi voltage eziguquguqukayo ezikhona wamanje kanye izonqunywa nomthamo capacitor bushelelezi.

rectifier okunjalo wesifunda kuchazwa kanje. Ukuze sinqobe ukuphazamiseka esiyinhloko transformer emazombezombe kuhlotshaniswa isihlungi, okuyinto yakhiwa capacitors ezimbili enamathiselwe iphuzu phakathi maqondana phansi. Balindeleke ukuba bakwazi unipolar, futhi ukunciphisa amathuba ukuhlukaniswa voltage ukalwe nganoma wabo 200 V

Ngokuvamile, switch isethelwe epholisayo, kubalulekile ukuvimbela voltage amapayipi ngesikhatsi kokuhlinzwa esikhathini capacitors rectifier. Fullwave rectifier transformer has a yesibili emazombezombe onompompi isikhungo, kodwa leli bhuloho wesifunda okukhipha akudingekile. Hlunga ngokuba rectifier kanye capacitor ezimbili uchungechunge Resistor. Nokho, izinga eliphansi yezwakala kwamukelekile ukwengeza enye capacitor okukhipha futhi Resistor.

Njengoba imishini kagesi usebenza ngokuvumelana isimiso reversibility, voltage rectifiers kanye inverter ezimbili zama- imishini kagesi. Ngokuthi kudivayisi inverter iguqula DC voltage ukuze AC.
