Imvamisa converters ngoba lokungeniswa izinjini: Umgomo we operation kanye nokugcinwa

Namuhla, imvamisa converters ngoba lokungeniswa motors avame ukusetshenziswa embonini. Kuyaphawuleka ukuthi lezi izinjini ube yabo Windings isakhiwo ezintathu, ezixhunywe kwi "inkanyezi" noma "unxantathu". Kodwa yayinesithiyo esisodwa - ulungise ijubane Rotor kunzima kakhulu. Kodwa elaliphambi. Manje, lapho iza ukusiza electronics micro namandla, lo msebenzi lula. Vula Resistor variable lingashintsha ijubane in ezahlukahlukene.

Lokhu kwakwenziwa ngayiphi injongo kuyadingeka imvamisa Converter?

Imisebenzi kulo mkhiqizo ziningi, kodwa iningi lemali elincane esetshenziswa. Empeleni, ukulawula imoto indlela kuyadingeka ukuze bakwazi ukulungisa hhayi kuphela ijubane ukujikeleza kodwa futhi ukusheshisa isikhathi, deceleration. Ngaphezu kwalokho, noma yiluphi uhlelo ludinga ukuvikeleka. Kuyadingeka ukuba acabangele zamanje imvamisa lokuguqulela, isebenzisa i motor lokungeniswa.

Kabanzi chastotniki e ukupholisa izinhlelo. Naphezu kalula okusobala isondo fan, umthwalo Rotor zinkulu kakhulu. Futhi ukusheshisa osheshayo akunakwenzeka. Futhi, kunezimo lapho isidingo ukwandisa isivinini ukujikeleza, ukugeleza komoya kwaba ngaphezulu noma ngaphansi. Kodwa lena kuphela isibonelo, Converter imvamisa livame ukusetshenziswa kwezinye izinhlelo. Nge chastotnika Ungavumelanisa ijubane elihambayo, ehlanganisa kudabuke eziningana.

Umgomo we operation ye imvamisa Converter

Isisekelo kuyinto ukulawula sekhompiyutha nezifunda eziningi yokuguqula AC futhi DC voltages. izinqubo eziningana zenzeka ne voltage okuyinto yanikezwa amandla okokufaka zedivayisi. Umsebenzi imvamisa Converter ilula, lwanele cabanga izigaba ezintathu. Okokuqala, kukhona eqondisa. Okwesibili, zokuhlunga. Okwesithathu, kombhala - ukuguqulwa of DC ukuze AC.

Kuphela ngesikhathi esiteji zokugcina Ungashintsha izakhiwo kanye izilungiselelo zamanje. Ngu obuhlukahlukene izici zamanje zingalawulwa ngu ijubane Rotor we motor indlela. In esigabeni inverter wasebenzisa inhlangano enamandla transistors. Lezi zici ezintathu O - amabili amandla nokulawula elilodwa. Kusukela ubukhulu bale isignali isetshenziswa yokugcina incike isici samanje yamandla aphindeke kabili ngesikhathi chastotnika okukhiphayo.

Ukuhamba ungayithola enye?

Imvamisa converters for izinjini indlela baqala ukusebenzisa esanda kutholakala. Kodwa isayensi kwaba kancane kancane kulokho kuqala Rotor ijubane ukujikeleza ukuthi nhlobonhlobo usebenzisa amagiya noma variator. Nokho, ukulawula onjalo kwakuyiNkosi nzima kakhulu, futhi amandla drive kungachithwa ngenxa izindlela ezingadingekile. Ziyisivikelo ukudluliswa kuyasiza ukwandisa isivinini kuphenduka, kodwa lokho ncamashi usethe nemingcele yokugcina kunzima kakhulu. Ngenxa yalezi zizathu, i VSD kungcono kakhulu ngoba ugwema ukulahlekelwa amandla. Kodwa okubaluleke kakhulu - it ikuvumela ukuba ushintshe idrayivu imingcele, ngaphandle kokushintsha Mechanics.

Yikuphi inverter ukukhetha ukusetshenziswa ekhaya?

Kufanele kuqashelwe ukuthi ukuxhumana kungaba kwenziwe kunethiwekhi esalisekela futhi ezintathu okhombisa zamanje. Konke kuncike othize drive imodeli, uma ngokuqondile, lapho isifunda inverter we motor lokungeniswa lisetshenziswe ukukhiqizwa. Ukuze uqonde isimiso ukusebenza, kwanele ukubheka isakhiwo zedivayisi. Eyokuqala iyunithi - a rectifier, okuyinto kwenzekani Semiconductor diodes. Lesi sifunda ibhuloho yokuguqula olulodwa noma ezintathu isigaba AC ukuze DC. Ukuze ikhaya zisebenzisa kumelwe ukhethe labo onobuhle chastotnikov kabani okokufaka axhunyiwe owodwa esigabeni iselulo segama lefayela. izinqumo ezihlobene ukuthi emakhaya abathile ukuze ukuqhuba inethiwekhi ezintathu okhombisa kuyinkinga, hhayi inzuzo, ngoba kumele usebenzise ezingcono akhawunti nempahla esebenza ngogesi.

The main izingxenye drive

Little Kuye kwathiwa circuit kuyinto inverter. Kodwa kudingeka ucabangele ke ngokuningiliziwe sesifundo somuntu enemininingwane. Esikhathini ukuguqulwa kuqala isigaba - AC ukulungiswa kwananoma. Kungakhathaliseki ukuthi kuningi kangakanani yesigaba okokufaka ihlinzekwa (elilodwa noma ezintathu), ngesikhathi ekhishwa rectifier uthola njalo unipolar (eyodwa plus nokukodwa lokususa) voltage ka 220 volts. Kuyinto kakhulu phakathi isigaba futhi singathathi hlangothi.

Lokhu kulandelwa iyunithi lemifanekiso, esiza balahle zonke izingxenye elibanzi wamanje kuyalungiswa. Futhi esiteji lokugcina is nabokhulumile - kusukela DC kuyinto variable esebenzisa transistors amandla, kulawulwa microcontroller. Ngokuvamile, inverters ngoba lokungeniswa motors abe ukubonisa ezinombala ofanayo LCD, elibonisa imingcele edingekayo.

Kungenzeka yini ukuba umuntu enze wena idivayisi?

Ukukhiqizwa zedivayisi lihlotshaniswa nobunzima obuningi. Udinga ukufunda izisekelo izinhlelo microcontrollers ukunweba amathuba insimbi. Kubalulekile ikhumbule zonke izidingo eziyisisekelo. Ngokwesibonelo, othomathikhi eziphuthumayo ukuvala shaqa lapho adlula ubukhulu kuvunyelwe zamanje okuyinto sokudliwa motor. Ukuze wenze lokhu, udinga ukusetha okukhiphayo Transformers samanje, siyofeza nokuqapha okuqhubekayo. Futhi, kufanele uhlinzeke yekwentiwa Ukupholisa izakhi kohlelo amandla - diodes futhi transistors, futhi ukukhubaza kudivayisi Ukushisa ngokweqile. Kuphela kuleli cala, imvamisa converters for izinjini indlela kungenziwa eziqhutshwa ngokuphepha.
