Inverter？
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.
Muri make, inverter nigikoresho cya elegitoronike gihindura voltage nkeya (12 cyangwa 24 volt cyangwa 48 volt) icyerekezo cyumubyigano muri volt 220 zisimburana. Kuberako dusanzwe dukoresha 220-volt ihinduranya ikosora kugirango tuyihindure muburyo butaziguye, kandi inverter ikora muburyo butandukanye, niyo mpamvu izina.
Niki asine wave inverter
Inverters irashobora gushyirwa mubice ukurikije ibisohoka byahinduwe, a. igabanijwemo indangantego ya kare, b. yahinduwe inverter na c. inine inverters.
Kubwibyo, ibisobanuro bya sine wave inverter ni inverter isohoka ibyasohotse ni sine wave.
Akarusho kayo nuko ibisohoka bisohoka nibyiza, kugoreka ni bike cyane, kandi ibyasohotse bisohoka ahanini bihuza na AC ya flake ya gride ya gride. Mubyukuri, ubwiza bwimbaraga za AC zitangwa nibyizasine wave inverterni hejuru kurenza iyo ya gride. Inverter ya sine ifite intambamyi nke kuri radio, ibikoresho byitumanaho nibikoresho byuzuye, urusaku ruto, imihindagurikire yimitwaro ikomeye, irashobora guhura nogukoresha imitwaro yose ya AC, kandi imashini yose ifite imikorere myiza; imbogamizi zayo nuko umurongo hamwe no kugereranya gukosora imivumba ihindagurika Inverter iragoye, ifite ibisabwa byinshi byo kugenzura imashini hamwe nubuhanga bwo kubungabunga, kandi bihenze.
Bikora gute?
Mbere yo kumenyekanisha ihame ryakazi ryasine wave inverter, banza utangire ihame ryakazi rya inverter.
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 ukabije wa TL5001 ni 3.6 ~ 40V, kandi ufite ibikoresho byongera amakosa, umugenzuzi, oscillator, generator ya PWM ifite igenzura rya zone yapfuye, umuzenguruko muke wo kurinda umuyaga hamwe n’umuzunguruko mugufi.
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 ka DIM, ntoya ibisohoka bigezweho bya inverter. binini.
Umuvuduko 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 yamakosa, oscillator na PWM, kurinda birenze urugero, kurinda amashanyarazi, kurinda amashanyarazi magufi, hamwe na transistor isohoka.
Guhindura DC: Umuyoboro wa voltage uhinduranya 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 AC Voltage.
LC ihindagurika hamwe n’ibisohoka: menyesha ingufu za 1600V zisabwa kugirango itara ritangire, kandi ugabanye ingufu za 800V nyuma yuko itara ritangiye.
Ibisohoka bya voltage ibisubizo: Iyo umutwaro urimo gukora, icyitegererezo cya voltage gisubizwa inyuma kugirango uhagarike ingufu za voltage ya I inverter.
Igishushanyo mbonera cya sine wave circuit
Itandukaniro riri hagati ya sine wave inverter na inverter isanzwe ni uko ibisohoka byamazi ari sine yuzuye hamwe nigipimo gito cyo kugoreka, bityo rero ntakabuza kubikoresho bya radio nibitumanaho, urusaku narwo ruri hasi cyane, umurimo wo kurinda urarangiye , kandi muri rusange imikorere iri hejuru.
Impamvusine wave inverterIrashobora gusohora sine yuzuye kuko ikoresha tekinoroji ya SPWM yateye imbere kuruta tekinoroji ya PWM.
Ihame rya SPWM rishingiye ku ihame rihwanye n’uko impiswi ikora ku bikoresho bikoresha igihe: niba impiswi ikora ku bikoresho bikora igihe, ibicuruzwa byagaciro kangana nigihe cyibikorwa bingana, kandi izo pulses zishobora kugereranywa zingana.
SPWM igereranya umuraba wa mpandeshatu hamwe ninshuro ihamye hamwe nigiciro cyagenwe cyagenwe (nko guhinduranya inshuro 10k) hamwe na sine wave (umurongo wibanze) wumurongo uhindagurika hamwe na voltage, kugirango uhindure imbaraga za DC (pulse hamwe nimpinduka zinshingano zakazi) ugereranije. icyerekezo cya sine kumurongo. Amplitude hamwe ninshuro byerekana sine yahinduwe kugirango habeho kubyara ingufu za DC voltage pulse ubugari bwa modulasiyo ihwanye na sine wave hamwe na amplitude hamwe na frequency zitandukanye.
