I-Sine Wave Inverter Ethuthukisiwe: Funda Ubuchwepheshe Obusemuva Kwayo

Esikhathini sanamuhla sedijithali, sincike kakhulu kumadivayisi kagesi ngezidingo zethu zansuku zonke. Kungakhathaliseki ukuthi sishaja i-laptop, sisebenzisa imishini yezokwelapha noma sisebenzisa nje izinto zasekhaya, umthombo wamandla othembekile nosebenzayo ubalulekile. Yilapho ama-inverter eqala khona ukusebenza, uhlobo olulodwa lwawo yi-modified sine wave inverter.

A i-inverter ye-sine wave eguquliweiyidivayisi eguqula ugesi oqondile webhethri ube ugesi oshintshanayo, okudingekayo ekusebenzeni kwamadivayisi amaningi kagesi. Ngokungafani ne-inverter ye-sine wave emsulwa, ekhiqiza ugesi obushelelezi nohambisanayo, i-inverter ye-sine wave eguquliwe ikhiqiza ugesi ohamba ngezinyathelo ofana negagasi lesikwele elinezinyathelo ezihlukile.

Ngakho-ke, kungani ukhethe i-modified sine wave inverter esikhundleni se-pure sine wave inverter? Impendulo itholakala ekuthengeni kwayo kanye nokuguquguquka kwayo.Ama-inverter e-sine wave aguquliwengokuvamile zisebenza kahle kakhulu kuneziguquli ze-sine wave ezihlanzekile, okwenza zibe ukukhetha okuthandwayo phakathi kwabathengi abaqaphela isabelomali. Kodwa-ke, kubalulekile ukuqaphela ukuthi akuwona wonke amadivayisi kagesi ahambisana neziguquli ze-sine wave eziguquliwe.

Inzuzo eyinhloko yama-inverter e-sine wave aguquliwe yikhono lawo lokunika amandla amadivayisi ahlukahlukene. Alungele ukusebenzisa izinto eziyisisekelo ezifana namafeni, izibani, namathuluzi kagesi. Ngaphezu kwalokho, angaphatha imithwalo yokumelana, okungukuthi, amadivayisi anezinga elinqunyelwe lokumelana, njengezibani zokukhanya ezi-incandescent. Ngakho-ke uma unesistimu yamandla yokusekela yezimo eziphuthumayo noma uhambo lokukhempa, i-inverter ye-sine wave eguquliwe ingase ibe ngcono.

Enye yezinto ezimbi ngama-inverter e-sine wave aguquliwe ukuhambisana kwawo nemishini kagesi ebucayi kakhulu. Amadivayisi athile, njenge-laptops, amaphilisi, kanye namadivayisi athile ezokwelapha, angase angasebenzi kahle futhi angase alimale ngisho nalapho exhunywe ku-inverter ye-sine wave eguquliwe. Lawa madivayisi adinga i-sine wave ehlanzekile, ebushelelezi ukuze asebenze kahle, yingakho kunconywa i-inverter ye-sine wave emsulwa kulezo zinhlelo zokusebenza.

Ukuze siqonde ubuchwepheshe obusemuva kwe-inverter ye-sine wave ethuthukisiwe, ake sibheke ngokujulile. Inqubo iqala ngomthombo wamandla we-DC, ngokuvamile ibhethri, onika amandla isekethe ye-pulse-width modulated (PWM). Le sekethe ikhiqiza isimo se-staircase waveform ngokuvula nokuvala i-voltage ngokushesha.

I-waveform ephumayo iqukethe izinyathelo ezishintshashintshayo ze-voltage ephezulu nephansi, yakha igagasi elingama-pseudo-sine. Nakuba lingase lingabi bushelelezi njengegagasi elihlanzekile le-sine, lisakwazi ukuletha amandla anele okusebenzisa i-electronics eyisisekelo ngaphandle kwezinkinga ezinkulu. Kodwa-ke, eminye imishini ye-elekthronikhi ebucayi ingase ibhekane nokuduma noma ukulahleka kokusebenza kahle uma ixhunywe ku-inverter ye-sine wave eguquliwe.

Abakhiqizi beama-inverter e-sine wave aguquliwebavame ukwengeza izingxenye ezengeziwe ze-elekthronikhi ukuze banciphise ukuphambuka kwe-harmonic futhi bathuthukise ikhwalithi ye-waveform. Lezi zingxenye zenzelwe ukunciphisa umthelela omubi ongaba khona kumadivayisi abucayi futhi zinikeze ulwazi olungcono kubasebenzisi. Kodwa-ke, kubalulekile ukukhumbula ukuthi ngisho nalezi zithuthukisi, igagasi le-sine eliguquliwe ngeke lihlanzeke futhi lihambisane njengegagasi le-sine elimsulwa.

Ngamafuphi, i-modified sine wave inverter iyisisombululo esingabizi kakhulu nesiguquguqukayo sokunika amandla izinhlobo ezahlukene zamadivayisi kagesi. Inikeza amandla anele okusebenzisa izinto eziyisisekelo kanye nemithwalo yokumelana. Kodwa-ke, ngenxa yesimo se-staircase esikhiqizayo, ingase ingafaneleki kuma-electronics azwelayo kakhulu. Ngaphambi kokukhetha phakathi kwe-modified sine wave inverter kanye ne-pure sine wave inverter, kubalulekile ukuqonda izidingo ezithile zemishini.
