Dc imbaraga za tekinoroji ya PWM, ibyiza nimbibi

Impinduka-ubugari bwa modulisiyo ni tekinike yo kugenzura igihe cyo kugereranya ibikoresho bya semiconductor ihinduranya muguhindura ubugari bwa pulse cyangwa igihe cyo kugenzura ibisohoka voltage. Kubera guhagarika neza kwandikirwa amajwi, igisubizo cyiza kigira imbaraga, ibyiza byingenzi mugihe cyinshi no gukora neza, cyakoreshejwe cyane muri inverteri ya elegitoroniki, kandi ikoranabuhanga ryarwo riragenda ritera imbere. Tekinoroji yo kugenzura PWM ikoreshwa cyane mumuzunguruko wa inverter, ifite uruhare runini kumuzunguruko. Kugeza ubu, umuzenguruko wa PWM ukoreshwa cyane cyane mumuzunguruko mwinshi. Muri make, urashobora guhagarika byoroshye ibisohoka voltage.

Nigute ikoranabuhanga rya PWM rikora?

Tekinoroji ya PWM nubuhanga bugenzura ibyasohotse mumashanyarazi muguhindura igihe cyo gutwara. Tekinoroji ya PWM mubisanzwe igera kumashanyarazi binyuze mumuzunguruko. Igenzura ryumuzenguruko rigenzura igihe cyo guhinduranya hashingiwe ku itandukaniro riri hagati y’ibisohoka n’umubyigano watanzwe kugira ngo ugere ku ntego ihamye ya voltage.

Ibyiza bya tekinoroji ya PWM

1. Umuvuduko uhoraho wa voltage

Tekinoroji ya PWM igenzura igihe cyo gutwara kugirango uhindure neza kugenzura ibisohoka voltage. Tekinoroji ya PWM ituma umusaruro wa voltage ugenzurwa neza kuruta uburyo bwa gakondo bwo guhinduranya umurongo, kunoza ituze no kwizerwa byuburyo bwa DC itanga amashanyarazi.

2. Kunoza imikorere yingufu

Ikoranabuhanga rya PWM rigabanya gutakaza ingufu muguhindura voltage yinjira mubimenyetso byinshi bya pulse. Muri icyo gihe, tekinoroji ya PWM irashobora kugenzura igihe cyo gutwara ibintu, kugabanya igihombo cya switch muri reta, bityo bikazamura ingufu zingufu.

3. Menya ibintu byinshi bisohoka

Mugucunga igihe cyo gutwara cya switch, tekinoroji ya PWM irashobora kugera kumurongo mugari wa voltage. Kurugero, mubikoresho bitanga ingufu za mudasobwa, tekinoroji ya PWM irashobora kugera kumashanyarazi atandukanye asohoka, nka 12V, 5V, na 3.3V, kugirango akemure ibikoresho bya elegitoroniki bitandukanye.

4. Gushyira mu bikorwa umutekano

Ikoreshwa rya tekinoroji ya pulse igenzura igihe cyo kuyobora kugirango igere ku kurinda ingufu. Kurugero, mubikoresho bya elegitoronike, tekinoroji ya PWM irashobora kurinda umutekano wibikoresho bya elegitoronike mugucunga igihe cyo guhinduranya hanyuma igahita ihagarika amashanyarazi mugihe voltage iri hejuru cyane cyangwa nkeya.

Imipaka yubuhanga bwa PWM

1. Urusaku rwinshi: Ikoranabuhanga rya PWM ritanga ibimenyetso byumuvuduko mwinshi wa pulse, bikunda kwangirika kwa electronique na urusaku, bigira ingaruka kumikorere isanzwe yibikoresho bya elegitoroniki.

2. Igiciro kinini: tekinoroji ya PWM isaba imiyoboro idasanzwe yo kugenzura no guhinduranya, kandi bihenze.

3. Ibisabwa cyane kubahindura: tekinoroji ya PWM isaba kwihuta cyane. Umuvuduko mwinshi wo guhinduranya imiyoboro ifite ibisabwa byinshi byo guhinduranya imiyoboro.

Muri make, tekinoroji ya PWM nubuhanga bukoreshwa cyane mugucunga uburyo DC itanga amashanyarazi. Ifite ibyiza byo gutuza neza, gukora neza, no kwizerwa cyane. Nyamara, tekinoroji ya PWM nayo ifite aho igarukira. Nkurusaku rwinshi, igiciro kinini, hamwe nibisabwa cyane kugirango tubone. Kubwibyo, kugirango wuzuze ibisabwa nibikoresho bya elegitoronike mugukoresha bifatika, birakenewe guhitamo tekinoroji ikwiye yo kugenzura ukurikije ibihe byihariye.
