The e tletseng e tsokoang rectifier, le kamoo e ea sebetsang

Rectifier bitsoa motlakase matla converters, tse semiconductor kapa tse ling tse sesebediswa elektroniki bakeng sa ho fetola lenaihana input matla a ho DC khumo. Tsokoang rectifier hahiloeng ka halofo-borokho kapa oa potoloho borokho, sebopeho e qaqileng ea tseo re tla tšohla.

Motheo oa sesebelisoa sa le tletseng tsokoang rectifier

Ho fetisisa a maqheka ana baka unidirectional ripple gagamalo. Ho boreleli ho pulsation, sebelisa filter e khethehileng.
Ho ntlafatsa entsprechen rectifier hlokahala hore ho fana ka phallo jwale bakeng sa halofo ea nako bobeli ea gagamalo input. Bakeng sa morero ona, mefuta e 'meli tsa lipotoloho sebelisoa halofo-e tsokoang rectification, eo sebetsa ka antiphase le ka synchronism le mojaro tloaelehileng.

Le kenyeletso ena hloka pedi mathomo gagamalo mohloding, e leng tla ba le ntlha e tloaelehileng. morero ona o bitsoa "e tletseng e tsokoang rectifier le ntlha bohareng." Boleng karolelano ea gagamalo ka resistors mojaro ka tletseng tsokoang rectification tsa litsupa joalo e tla feta ka makhetlo a mabeli le halofo e tsokoang potoloho.

Re lokela ho hlokomela hore dvuhpolupeiodnoy merero e nang le midpoint, o na likarolo tse lona negative. Ha morao-rao le fetisa diode e mong ka ho se fapaneng khutlisetsang gagamalo tlhōrō ka mohato fihla palo e kahodimodimo ea habeli ka gagamalo input, re lokela ho a hopola khetha diodes bakeng rectifier ena.

Ntlheng ena, nahana ka boitsebiso bo eketsehileng e tletseng e tsokoang rectifier oa potoloho ho ba le tšepe e dikahare ho ba le e kholo a sebetsang a lekanang le ka hare ho hanyetsa. Sena se etsa hore ho ba teng ha tahlehelo kgolo amanang le futhumatsang bohlokoa ea transformer le.

Ka ho haha joalo ea potoloho ho ba le smoothing capacitor, ho ke ke ho hlokahala hore ba nahane ka hore ka tekanyo fapanyetsana gagamalo eona, kamehla e melemo ho sebelisa mehaho, tse haholo nyenyane ho feta molumo lebetsoeng le. Ho ba sieo ha mojaro ka capacitor eo gagamalo phosollwa ke kamehla lekanang molumo. Sena se bolela hore e tletseng e tsokoang rectifier le e le 'ngoe-mohato fapanyetsana jwale ya capacitor 12, ha ho na mojaro fumana gagamalo la 17 V. From ena, re ka etsa qeto ea hore tlas'a mojaro oa ka gagamalo phosollwa decreases, empa ha ba ka tlaase ho e gagamalo divariabole jaana hona joale le tla ikemisetsa ka matla a ka smoothing capacitor.

Joalo rectifier oa potoloho o hlalosoa ka tsela e latelang. E le hore ho thibela tshitsiso ea transformer mathomo matsoelintsoeke e hokahantsoeng ke ho filthara, e entsoe ka capacitors tse peli le khomaretse bohareng ntlha ikutloeleng fatše. Ba lokela ho monopolar, le ho fokotsa ho sithabela kgonego ya ho gagamalo rated ka bona ke 200 V.

Ka tloaelo ho, switjha ho e behiloeng ka ho condenser, e ke ho hlokahala hore a thibile e timang gagamalo nakong tshebetso ka capacitors rectifier. Fullwave rectifier transformer e na le se mahareng matsoelintsoeke le setsi sa pompo ea, empa ena borokho oa potoloho khumo ha ho hlokahale. Filtara bakeng sa rectifier le capacitor tse pedi letoto la lihlooho tse resistor. Leha ho le joalo, e le boemo ba tlaase ba ripple oa amoheleha ho eketsa e mong capacitor khumo le resistor.

Kaha mechine ea motlakase e sebetse ho latela molao-motheo oa reversibility, rectifiers gagamalo hammoho inverter ho na le mefuta e 'meli ea mechine ea motlakase. Bitsoa inverter sesebediswa fetola DC gagamalo ho lenaihana.
