Driving nomoto inverter. Schematic dhayagiramu of inverter chakanamwa nomoto

Nyaya ichakurukurwa munhu chaiwo zano kuti nomoto inverter. To musi, vane mukurumbira kwazvo, mutengo Zvakwana zviripo. Vane yakawanda hwakanaka, hwakadai vakasununguka kushanda uye vakaderera uremu. Asi, kufanana nezvimwe zvigadzirwa zvokushandisa, nomoto muchina anogona sousingabatsiri. Uye kuti aite unhu kugadziriswa, zvakakodzera kanenge zvavo nemashoko, vane pfungwa nechivako kwayo, chii zvinhu rinoumbwa inverter redunhu. Pasina izvozvo, iwe havazokwanisi kugadzira svarochniki ari anorimwa iyo inoshandisa inverter transformers. Naizvozvo, unofanira kudzidza zvakawanda dzidziso pamusoro mudziyo uyu.

Basic ruzivo pamusoro inverter midziyo

Kutaura chokwadi, simba iri chikwata, ayo uchishandisa pfungwa akafanana akashandiswa oga makombiyuta. Kutendeutsa zvemagetsi simba kunoitika pamusoro chete mazano, pasinei nokuti ukuru uye kushanda izvi siyana mano. Pane matanho anoverengeka kuitika chakanamwa nomoto inverter. Chokutanga pane rakatumbuka voltage kuchinja iyo kusvitsa pamutsetse 220 kuva DC. About sei izvi zvaitika, uchadzidza zvishoma pazasi, uyewo chinoratidza wedunhu dhayagiramu ane nomoto inverter.

Zvadaro rokutendeutsa voltage ichi rikaitika shanduka, asi ane yepamusoro maitikiro. Munoziva kuti mains kuitika kakawanda 50 Hz. The inverter nomoto midziyo ndiko kuwedzera 80 Hz tysyach. Zvino zvakafanira kuti kuderedza voltage chamunowana refu maitikiro. Pakupedzisira danho iri kuchinja yakaderera voltage ane kakawanda vanenge 80 Hz tysyach. pfupiso iri, Chokwadi, vose mumatanho vanogona dzichakoromorwa madiki zvinoriumba. Asi kunzwisisa nheyo inoshanda yakakwana.

Pakudaro kuderedza uremu chakanamwa nomoto muchina

Zvino, dunhu nei akasarudzwa ane inverter mhando. Tsvaka Welding michina izvo zvave kare, kusanganisira mukaravhani. chinangwa chavo chikuru - kuderedza AC voltage iri yaipiwa kubva mhuri zvemagetsi nzira yokubudisa kune ngozi ukoshi, asi ane yechipiri kuitika guru. Nokuda kwechikonzero ichi, zvikuru ichitenderera iri muchikuvadza wakawondereiko kudai mazuva ose waya kupfuura yechipiri. Pakukora ari waya kunobva sei zvikuru kuitika Unopinda muna ichitenderera. Pasi riri schematic Mufananidzo imwe nomoto inverter munyaya. Nyatsodzidza nayo, kuva pfungwa chii zvinhu kupinda mariri. Welding dzimwe nguva crawled anoverengeka zana amperes. Nokuti kuti simba transformers dzakadaro yakakwirira kwazvo, asi vanoshanda chete apo magetsi kakawanda 50 Hz, mukuwedzera, vane guru kwazvo saizi. Sezvaungafungidzira, kakawanda pakati mazano uye goho Kuyerera chete. Nemamwe mashoko, kana kureva chikuru ichitenderera 50 Hz, dzisiri bvisa Magetsi pamwe chete parameters.

The kushanda kakawanda pakati inverter

Asi ikozvino nemhaka inverter nomoto muchina, iyo inowedzera uchishandisa kakawanda pamusoro hurongwa zviuru makumi masere Hertz, uye mune dzimwe namano uye zvakawanda, unogona kuva nguva zhinji kuderedza kukura transformers, izvo anoshandiswa kutendeuka magetsi ano. Kana iwe kuwedzera uchishandisa kakawanda, ari transformer inogona kuderedzwa kanokwana kana. Naizvozvo, zvachose kurema svarochnika zvose zvichava zvikuru duku. Mari mutengo mudziyo uyu zvakare akaderedzwa, sezvo pane aponese mhangura uye simbi, izvo akashandiswa zvaAtemisi transformers. Asi kuwana kakawanda zvakadaro, unofanira kushandisa inverter matunhu. Zvinosanganisira mukuru-simba munda-Chaizvoizvo transistors kuti ushande anokosha nzira. Uchibatsirwa wavo, magetsi ari kushandisa kubva kakawanda zvaidiwa oparesheni. Tapota ona kuti basa anogona chete FET pane kugara voltage. Zvinokosha kucherechedza kuti "Resanta" kurongerana nomoto inverter zvikuru chakafanana nechakashandiswa mune dzimwe namano.

The kushanda nheyo rectifier

Saka, usati kushandisa simba kwavari, zvakakodzera kutwasanudza huri kuuya uno. Nokuti ichi chinangwa ane rectifier, sezvamakaropafadzwa diodes vane simba. Vari zvakabatana mune zambuko redunhu. Zvadaro vari cutoff shanduka zvinoriumba kushandisa electrolytic capacitors. Izvi zvinoitika pakutanga kutendeuka rwakazara. Field maturo transistors chokuita kuti transformer. Achibatsirwa vakachiwana ezasi voltage. Sezvataurwa pamusoro apa, transistors izvi pave ano nokuchinja ari kakawanda dzimwe nguva kunyange kupfuura 80 tysyach Hz. Zviri pachena kuti transformer anofanirawo akagadzirirwa kushanda pasi parameters izvi. Kukura mudziyo uri vashomashoma, kwete enzanisa pamwe nezvaishandiswa mune kwakajairika transformer nomoto michina. Asi simba zvaanazvo ndiye. Zviri pachena kuti pane nzira dzakawanda zvinhu zvinodiwa mudanga kushanda chakanamwa nomoto muchina. Zvino zvose zvakawanda nezvokuti sei neimwe block kwakajairika nomoto inverter. Rine huru zvikamu zviviri - simba uye kudzora redunhu.

rectifier rwakazara

misa ichi kunoitika AC kutendeuka uko anosvika kubva zvakarukwa 220 volts. Mariri, pane dzakawanda semiconductor diodes dzakakwirira simba, uyewo electrolytic capacitors uye inductor. Izvi machira anopa chii rakatumbuka pari ane uchishandisa kakawanda 50 Hz anova dzose. Capacitors inodiwa kucheka shanduka zvinoriumba, riri achiri kunogadzirisika voltage. Tapota ona kuti pane nzira dzakawanda kuti kugadzirisa zviri voltage matunhu. Kana kubatana anofanira kuti-danho matatu network, dunhu Mufananidzo semiconductor diodes vachava siyanei. Naizvozvo zvakafanira kuti kuona kuti zvaunoda nomoto inverter redunhu. Nemaoko avo, zano rakadaro inogona vakaungana nyore.

Cherechedza kuti mune inenge hafu voltage inowedzerawo shure anoenda Sefa, yakaunganidzwa pamusoro electrolytic capacitors. Nemamwe mashoko, kana paine mains nerubatsiro 220 volts, ipapo capacitor zviteshi, kana waita kuyerwa, ndizvo 310 V. Kuti chechetere kuitika ripple kudzivisa chero mukuru-kakawanda ruzha, uyewo kudzivisa kwavo vasawira simba afoot, zvinokosha hwokugadza chinokosha firita. Kazhinji iri kuenda throttle kuti vanga Zamok chinoumba uye redunhu zvinosanganisira capacitors akawanda.

inverter rwakazara

Kazhinji, nokuti Implementation pamusoro inverter kushandisa miviri simba transistors kuti ushande anokosha nzira. Zvinokosha kucherechedza kuti vachanzwikwa akatasva aruminiyamu kupisa singi. Uyewo, pane chimwezve kumanikidzwa kutonhora ane feni. Nokuda transistors izvi anogona kubatanidza DC voltage, iyo zvino zvokudya kune Ropa transformer. Zvakare, nokuchinja kunoitika ane kakawanda vanenge 80 kHz. Asi pane musiyano kubva rakatumbuka pari inoyerera mumusha simba nechimwe. Chekutanga, kakawanda mutengo pacharo kakawanda runopfuura payo. Chechipiri, kurova kwemwoyo Maumbirwe rakatumbuka voltage riri vanowanika FETs rectangular pane sinusoid. Kudzivirira transistors rokurara overvoltage, zvakakodzera kushandisa dunhu rine resistors uye capacitors. Zvinofanira kucherechedzwa kuti wedunhu dhayagiramu pamusoro inverter chakanamwa nomoto haisi pasina zvinhu iwayo.

RF transformer

High-kakawanda transformer, uko mumwe voltage kubva transistors kushanda nokuchinja muoti, saka achidzikisa kukosha kwayo kuti 65 volts paavhareji. Asi ichi pari vangava sezvakarayirwa 130 A. Zvinoita kunyange kuzochera imwe Ringanidzo pamwe kuvesa coils, iyo inoshandiswa motokari. The nomoto inverters kuti chinonyanya ichitenderera munhu mukuru voltage, asi magetsi ane chaizvo diki chete. Zvinonzi kubva yechipiri ichitenderera voltage kuti ukoshi yakaderera, asi pari inowedzerwa. Tapota ona kuti motokari kuvesa coils inoshanda neizvi musimboti. Kuti, rakadzika voltage guru iyezvino ari kusvitsa kune chepuraimari ichitenderera. A rinobviswa dzisiri mukuru voltage, asi ane zviduku ano ukoshi.

The goho rectifier

Asi zvinokosha kuti kutarisa zvakaita zvinoumba mamwe e-mail. Welding inverter redunhu. Panguva goho pamusoro rectifier kuripowo wakaiswa, riri inounganidzwa kubva kumusoro-simba semiconductor diodes. Vane refu kwazvo pakukurumidza, vari akazarurwa uye kuvharwa panguva, inova shoma zvikuru pane 50 nanoseconds. Ona magadzirirwe nomoto inverters kuti vanofanira osimudza semiconductor zvinhu nenzira yakadaro kuti kugutsa parameters kushanda. Simple diodes haangavi kutsungirira basa, sezvo ivo havazokwanisi kuvhura uye pedyo nenzira nenguva nenzira. Pakarepo tanga kunyanyisa kudziyisa uye, naizvozvo, kukundikana. Nokuda kwechikonzero ichi, magadzirirwo kana kugadzwa rokugadzirisa kubudisa diodes, vane pfupi chaizvo nokuchinja nguva.
