Hamwe niterambere ryikoranabuhanga rigezweho, kugaragara kwa inverter byatanze ibyoroshye byinshi mubuzima bwa buri wese, none inverter niki?Nigute inverter ikora?Inshuti zishishikajwe nibi, ngwino ushakire hamwe.
Inverter ni iki:
Inverter ihindura imbaraga za DC (bateri, bateri yo kubika) mumashanyarazi ya AC (muri rusange 220V, 50Hz sine wave).Igizwe nikiraro cya inverter, kugenzura logique no kuyungurura.Byakoreshejwe cyane mubyuma bifata ibyuma bikonjesha, inzu yimikino, inzu zogusya amashanyarazi, ibikoresho byamashanyarazi, imashini zidoda, DVD, VCD, mudasobwa, TV, imashini imesa, ingofero, firigo, VCR, massage, abafana, amatara, nibindi mubihugu byamahanga, kubera ku gipimo kinini cyo kwinjira mu binyabiziga, inverter irashobora gukoreshwa muguhuza bateri kugirango itware ibikoresho byamashanyarazi nibikoresho bitandukanye byo gukora mugihe ugiye kukazi cyangwa gutembera.
Ihame ry'imikorere ihindagurika:
Inverter ni DC kuri AC transformateur, mubyukuri ni inzira ya voltage ihindagurika hamwe nuhindura.Ihindura ihindura AC voltage yumuriro wa gride mumashanyarazi ahamye 12V DC, mugihe inverter ihindura 12V DC yamashanyarazi na Adapter mumashanyarazi menshi yumuriro mwinshi;ibice byombi binakoresha tekinike ikoreshwa cyane ya pulse ubugari (PWM).Igice cyacyo cyibanze ni PWM igenzurwa, Adapter ikoresha UC3842, naho inverter ikoresha chip ya TL5001.Umuvuduko wakazi wa TL5001 ni 3.6 ~ 40V.Ifite ibikoresho byongera amakosa, umugenzuzi, oscillator, generator ya PWM hamwe na zone yapfuye, umuzenguruko muke wo gukingira umuyaga muke hamwe n’umuzunguruko muto.
Igice cyinjiza igice:Hano hari ibimenyetso 3 mubice byinjiza, 12V DC yinjiza VIN, akazi gashobora gukora voltage ENB na Panel igenzura ibimenyetso DIM.VIN itangwa na Adapter, voltage ya ENB itangwa na MCU kurubaho, agaciro kayo ni 0 cyangwa 3V, mugihe ENB = 0, inverter idakora, kandi iyo ENB = 3V, inverter iba mumikorere isanzwe;mugihe voltage ya DIM Itangwa nubuyobozi bukuru, itandukaniro ryayo riri hagati ya 0 na 5V.Indangagaciro zitandukanye za DIM zigaburirwa gusubira mubitekerezo byanyuma bya PWM mugenzuzi, kandi ibyatanzwe na inverter kumuzigo nabyo bizaba bitandukanye.Gutoya agaciro DIM, ntoya ibisohoka bigezweho bya inverter.binini.
Umuyoboro wo gutangiza amashanyarazi:Iyo ENB iri murwego rwo hejuru, isohora voltage nyinshi kugirango imurikire umuyoboro winyuma wa Panel.
Umugenzuzi wa PWM:Igizwe nimirimo ikurikira: voltage yimbere yimbere, amplifier yibeshya, oscillator na PWM, kurinda birenze urugero, kurinda amashanyarazi, kurinda imiyoboro ngufi, hamwe na transistor isohoka.
Guhindura DC:Umuzunguruko wa voltage ugizwe na MOS guhinduranya umuyoboro hamwe nububiko bwo kubika ingufu.Iyinjiza ryongerwaho imbaraga na push-pull amplifier hanyuma igatwara umuyoboro wa MOS kugirango ikore ibikorwa byo guhinduranya, kugirango DC yumuriro wa DC ikurekura inductor, kugirango urundi ruhande rwa inductor rushobore kubona voltage ya AC.
LC ihindagurika no gusohora ibintu:menyesha ingufu za 1600V zisabwa kugirango itara ritangire, kandi ugabanye ingufu za 800V nyuma yuko itara ritangiye.
Ibitekerezo bya voltage bisohoka:Iyo umutwaro urimo gukora, icyitegererezo cya voltage gisubizwa inyuma kugirango uhagarike ingufu za voltage ya inverter.
