Full-wave rectifier uye kushanda kwayo

Anogadziridza ishanduko yemagetsi, iyo inonzi semiconductor kana electrovacuum iyo inoshandura imwe nzira yekushandisa inoita kuti ive nguva dzose. Mugadziri wegadziri akazara wakavakwa pahafu yebhiriji kana bhiriji circuit, tsanangudzo yakajeka yatichakurukura.

Essence uye urongwa hwehuwandu hwemagetsi

Zvizhinji zvezvigadzirwa izvi zvinoumba unidirectional pulsating voltage. Kuti ubvise ruzha, shandisa mafaira anokosha.
Kuvandudza mamiriro ekugadzirisa, zvakakosha kuoneka kuti ikozvino kuyerera kusvika kumapfumbamwe emazuva emagetsi ekushandisa. Nokuda kwechikonzero ichi, mavara maviri ehafu-wave rectification circuits anoshandiswa , ayo anoshanda muchikamu uye sechinyorwa nemutoro mumwe chete.

Nekushandura kwaunoita iwe uchada maviri makuru emagetsi ayo achave nenheyo yakafanana. Iri chirongwa chinonzi "full-wave rectifier neveji yepamusoro". Muchiitiko ichi, muvhareji wehutengo hwemagetsi mu-load resistors munguva yakazara-wave kugadziriswa ichapfuura kaviri matanho akafanana ehafu-wave circuit.

Izvo zvinofanira kuonekwa kuti maviri-hafu-cycle cycle, iyo ine chiyero chepakati, ine nhengo dzisina kunaka. Apo iyo yemazuva inopfuura imwe diode, kune rumwe rutivi, rutivi rwemhepo inopera mukati mechikamu chepamusoro rinosvika kune zvakapetwa zvakapetwa zvakapetwa kaviri, izvo zvinofanira kuyeukwa pavanosarudza diod kuti vadzose.

Panyaya iyi, tichaongorora nekunyatsotsinhirana kwekugadzirisa-wave kugadzirisa, iyo ine dare-yakasimba yedunhu ine simba guru rinoshandiswa rinopindira mukati. Izvi zvinokonzera kuvapo kwekurasikirwa kwakakura kunobatanidza nekupisa kukuru kwekushandura kwemhepo.

Pakuvaka dunhu rakadaro ne-smoothing capacitor, zvakakosha kufunga kuti kuyera kwemhepo inoshandiswa nguva dzose kunowanikwa pamagariro anobudirira, ayo ari maduku zvikuru kudarika marefu amplitude. Kana kusina mutoro pa-capacitoritor, iyo yakagadziriswa magetsi nguva dzose yakaenzana neyakakura yemagetsi. Izvi zvinoreva kuti chigadziri chemugadziri wegadziriro imwechete yechine-rimwe gasi rinoshandiswa ikozvino 12 V pane a capacitor richawana gorosi rakaenzana ne17 V. Kana pasina mutoro, gasi re 17 V rinogona kuwanikwa.Kubva pane izvi, zvinogona kugumiswa kuti pasi pemutoro, maitiro akagadziridzwa anodzika, asi haasi pasi peiyo iripo yakawanda yevashanduri Currents uye ichagadziriswa nekwaniso ye shandisa capacitor.

Dunhu remugadziri akadaro rinogona kurondedzerwa sezvinotevera. Kuti tidzivirire runyararo, mhepo inonyanya kushandiswa ye transformer inosanganiswa nefaira, iyo inoumbwa nema-capacitors maviri nepakati yakaiswa pasi. Izvo chaizvoizvo zvinonzi unipolar, uye kuitira kuti kuderedze mikana yekuputsika, mazita avo emagetsi anonzi 200 V.

Kazhinji, kuchinja kunosungirirwa pamberi pegadziri, iyo inofanirwa kudzivirira kupiwa kwemaoko emagetsi apo anoruramisa ari kushanda pavanokwanisa. Mugadziri wegadziri akazara ane shanduro yechipiri ye transformer nebhokisi rekati, asi hapana chidikaniso chebhiriji mudunhu iri. Iyo firitsi yekugadziridza ndeyeviri capacitors uye nyaya inopesana. Zvisinei, nehutsika hwechibhakera, zvinotenderwa kuwedzera imwezve capacitor uye kukwikwidza kune zvakabuda.

Sezvo makemikari emagetsi ari kuita maererano nehutano hwekudzoka, kugadzirisa magetsi Pamwe pamwe ne inverter kune mhando mbiri dzemagetsi emagetsi. An inverter chinhu chinoshandura gumbo rinogara richienda kune rimwe rinopisa.
