Inverter ni iki?
Inverter ihindura DC Power (bateri, bateri yububiko) mu mbaraga za AC (muri rusange 220v, 50hz SINE WAVE). Igizwe nikiraro cyinzogera, kugenzura logique noyunguruzo.
Muri make, inverter nigikoresho cya elegitoroniki gihindura voltage nkeya (12 cyangwa 24 volt) kumurongo uyobora muri 220 volt gusimbura ubu. Kuberako mubisanzwe dukoresha 220-volt guhinduranya impinduramatwara kugirango tuyihindure muburyo butaziguye, kandi mubyukuri ibikorwa muburyo bunyuranye, niyo mpamvu izina.
Inverter irashobora gushyirwa mubikorwa ukurikije ibisohoka. Bigabanijwemo kare kare Yahinduwe Abahengeri na c. Sine Wave.
Kubwibyo, ibisobanuro bya sine waveter ni insimburangingo yumurongo usohoka ni umuraba.
Inyungu zayo ni uko kwimura ibisohoka nibyiza, kugoreka ni bike cyane, kandi umugera wacyo uhuye ahanini na AC kuzunguza k'urutasigi. Mubyukuri, ubuziranenge bwimbaraga za AC zitangwa nibyizaSine Wave Inverterni hejuru yiya gride. Interiner yumuraba ntabwo yirengagije kuri radio, ibikoresho byitunganyirizwa hamwe nibikoresho biri hasi, urusaku rukomeye, rukomeye rwo guhuza n'imikorere, kandi imashini yose ifite imikorere minini; Ibibi byayo nuko umurongo kandi ukosora umugozi uhindura inverfer ni bigoye, bifite ibisabwa byinshi kugirango ugenzure chip no gukorana na tekinorono, kandi bihenze.
Nigute ikora?
Mbere yo kumenyekanisha ihame ryakazi ryaSine Wave Inverter, banza utangire ihame ryakazi ryaboherwa.
Inverter ni dc kuri AC irahindura, mubyukuri nuburyo bwo guhindagurika voltage hamwe numwuka. Guhindura Guhindura AC voltage ya ac muri grid ya 12v DC ihagaze neza, mugihe inverteri ihindura ibyakozwe na 12v DC ya Voltage ya Adaptor mumashanyarazi maremare-voltage ac; Ibice byombi nabyo bikoresha kenshi gukoreshwa module ya Pulse (Tekinike ya PWM). Igice cyayo cyibanze ni umugenzuzi wa PWM urimo, adapter ikoresha UC3842, kandi inverter ikoresha TL5001 chip. Umukozi ukora cyane wa TL5001 ni 3.6 ~ 40V, kandi ifite ibikoresho byongeraho Amplifier, umugenzuzi, ikiganiro cya PWM hamwe nu muzunguruko wo muri voltage hamwe numuzunguruko muto wo kurinda volt.
Imigaragarire yinjiza igice: Hano hari ibimenyetso 3 mucyiciro cyashize, 12v DC yinjiza vin, akazi gafasha enb enb na panel igenzura ryibimenyetso. Vin itangwa na adapt, enb voltage yatanzwe na MCU ku kibaho, agaciro kayo ni 0 cyangwa 3V, inverter ntabwo ikora, kandi inverter iri muri leta isanzwe; Mugihe wangiza voltage yatanzwe ninama nkuru, urwego rwimyitwarire rwarwo ruri hagati ya 0 na 5v. Indangagaciro zitandukanye zigaburirwa kubitekerezo byibitekerezo bya PWM umugenzuzi, kandi ubu byatanzwe nitsinda ryumutwaro nabyo bizaba bitandukanye. Gitoya agaciro gake, ntoya ibisohoka kurubu. binini.
Impumuro Yumuziki: Iyo Enb iri kurwego rwo hejuru, isohoka voltage ndende kugirango imurikire umuyoboro winyuma.
Umugenzuzi wa PWM: Igizwe n'imikorere ikurikira: Imbere Yimbere, Ikosa Amplifier, OsiLillator na PWM, kurengera byinshi, kurinda ibintu bitunguranye, kurinda umutego.
DC Ihinduka: Umuzunguruko wa voltage ugizwe na mos guhinduranya igituba no kubika ingufu. Iyinjiza yinjiza irakorozwa no gukurura amplifier hanyuma hanyuma itwara miss umuyoboro wo gukora guhindura ibintu, kugirango amafaranga ya DC aregwa kandi asohore innguramu, kugirango urundi ruhande rwinjira rushobore kubona ac voltage.
LC OSCALLALAS N'IKIMENYETSO CYIZA: Menya neza voltage ya 1600v isabwa kumatara yo gutangira, kandi ugabanye voltage kuri 800v nyuma yitara itangira.
Ibisohoka ibitekerezo bya voltage: Iyo umutwaro ukora, vopiseling voltage yahagaritswe kugirango ihuze na voltage ibisohoka muri nderter.
(Bigoye sine igishushanyo mbonera)
Itandukaniro riri hagati yumurongo wa sine kandi uhindagurika ni uko imigezi yacyo yuzuyemo imitingi yose, bityo ntangarugero kubikoresho byituro, urusaku narwo ruri hasi cyane , kandi imikorere muri rusange ni ndende.
Impamvu ituma UwitekaSine Wave InverterIrashobora gusohoka icyumba cyuzuye sine ni ukubera ko ikoresha tekinoroji ya spwm iteye imbere kuruta ikoranabuhanga rya PWM.
Ihame rya spwm rishingiye kumahame ahwanye niho dupakiye kumwanya wigihe cyigihe: Niba impimuro ikora mugihe cyibikoresho byigihe, ibicuruzwa byibikoresho bingana, kandi igihe cyibikorwa kirashobora kugereranywa kugirango gisa nki gihwanye.
Spwm igereranya imiraba ya mpandeshatu ifite inshuro zihamye hamwe nagaciro gakomeye (nko guhinduranya inshuro 10k) hamwe na voltage) yimyumbati ya dc (pulse hamwe nimisoro yizuba) Ibisobanuro byubaze kubikoresho. Amplitude na konsa yo kwerekana imigezi ya DC pultage false False igereranya imirongo ihwanye na sine wine wine hamwe nimpyisi zitandukanye.
