Inverter ni iki?

Inverter ni transformer ya DC kuva kuri AC, mu by'ukuri ikaba ari inzira yo guhindura voltage hamwe na converter. Converter ihindura voltage ya AC y'umuyoboro w'amashanyarazi mo 12V DC ihoraho, mu gihe inverter ihindura voltage ya 12V DC iva kuri adaptateri ikayihindura AC ifite voltage nyinshi; ibice byombi binakoresha ikoranabuhanga rikoreshwa cyane mu guhindura pulse width modulation (PWM). Igice cy'ibanze ni controller ya PWM, adaptateri ikoresha UC3842, naho inverter ikoresha chip ya TL5001. Ingano y'amashanyarazi ya TL5001 ni 3.6 ~ 40V, kandi ifite amplifier y'amakosa, regulator, oscillator, moteri ya PWM ifite dead zone control, circuit yo kurinda voltage nke na short circuit protection circuit.

Igice cyo kwinjiza: Igice cyo kwinjiza gifite ibimenyetso 3, VIN yinjiye ya 12V DC, amashanyarazi ENB ikora hamwe n'ikimenyetso cyo kugenzura umuyoboro wa Panel DIM. VIN itangwa na Adapter, naho voltage ya ENB itangwa na MCU kuri motherboard, kandi agaciro kayo ni 0 cyangwa 3V. Iyo ENB = 0, inverter ntikora, naho iyo ENB = 3V, inverter iba ikora neza; naho voltage ya DIM itangwa na motherboard, kandi intera yayo iri hagati ya 0 na 5V. Ingano zitandukanye za DIM zisubizwa ku mpera y'umuyoboro wa PWM, kandi umuriro utangwa na inverter ku mutwaro nawo uzaba utandukanye. Uko agaciro ka DIM kaba gato, niko umuriro usohoka na inverter uba munini.

Umuyoboro wo gutangira voltage: Iyo ENB iri hejuru, voltage nyinshi irasohoka kugira ngo imurike umuyoboro w'urumuri rw'inyuma rw'urumuri.

Umugenzuzi wa PWM: Ugizwe n'imirimo ikurikira: voltage y'imbere, amplifier y'amakosa, oscillator na PWM, kurinda overvoltage, kurinda undervoltage, kurinda short circuit, na transistor y'ibisohoka.

Guhindura DC: Urugendo rwo guhindura voltage rugizwe na MOS switch tube na inductor yo kubika ingufu. Ingufu zo kwinjira zongerwaho na amplifier ya push-pull maze igatuma MOS tube ikora igikorwa cyo guhindura, kugira ngo DC voltage ishyushye kandi isohora inductor, ku buryo urundi ruhande rwa inductor rushobora kubona voltage ya AC.

Uburyo bwo gusohora no kuzunguruka kw'amashanyarazi bwa LC: reba neza voltage ya 1600V ikenewe kugira ngo itara ritangire, kandi ugabanye voltage ya 800V nyuma y'uko itara ritangiye.

Uburyo voltage isohoka: iyo umutwaro urimo gukora, voltage yo gupima isubizwa inyuma kugira ngo ihamye voltage isohoka ya inverter ya I.

Imikorere
Inverter ihindura ingufu za DC (bateri, bateri yo kubika) mo ingufu za AC (muri rusange 220v50HZ sine cyangwa wave kare). Mu magambo ya layman, inverter ni igikoresho gihindura amashanyarazi agororotse (DC) mo amashanyarazi asimburana (AC). Igizwe n'ikiraro cy'amashanyarazi, logike yo kugenzura na circuit ya filter.
Mu magambo make, inverter ni igikoresho cy'ikoranabuhanga gihindura ingufu za DC zifite voltage nke (volts 12 cyangwa 24 cyangwa volts 48) zikajyamo ingufu za AC za volts 220. Kubera ko ingufu za AC za volts 220 zikunze guhindurwamo ingufu za DC kugira ngo zikoreshwe, kandi uruhare rwa inverter ni ikinyuranyo, niyo mpamvu izina rivugwa. Mu gihe cy' "ingendo", ibiro bigendanwa, itumanaho rigendanwa, imyidagaduro igendanwa n'imyidagaduro. Iyo uri mu rugendo, si umuriro ugororotse ufite voltage nke gusa ukenewe muri bateri cyangwa bateri zo kubika, ahubwo no muri volts 220 zisimburana, ari ngombwa cyane mu buzima bwa buri munsi. Inverters zishobora guhaza ibyo bikenewe.
