Chosinthira Mafunde cha Sine Wave Chokonzedwa Bwino: Phunzirani Ukadaulo Womwe Uli M'mbuyo Mwake

Masiku ano, timadalira kwambiri zipangizo zamagetsi pa zosowa zathu za tsiku ndi tsiku. Kaya tikuchaja laputopu, kugwiritsa ntchito zida zachipatala kapena kungogwiritsa ntchito zipangizo zapakhomo, gwero lamphamvu lodalirika komanso logwira ntchito ndilofunika kwambiri. Apa ndi pomwe ma inverter amagwira ntchito, mtundu umodzi womwe ndi modified sine wave inverter.

A inverter ya sine wave yosinthidwandi chipangizo chomwe chimasintha mphamvu ya batri yolunjika kukhala mphamvu yosinthira, yomwe imafunika kuti zipangizo zambiri zamagetsi zizigwira ntchito. Mosiyana ndi inverter ya thonje ya sine, yomwe imapanga mawonekedwe osalala komanso ogwirizana, inverter ya sine wave yosinthidwa imapanga mawonekedwe oyenda pang'onopang'ono omwe amafanana ndi mafunde a sikweya okhala ndi masitepe osiyana.

Ndiye, bwanji kusankha chosinthira mafunde a sine m'malo mwa chosinthira mafunde a sine? Yankho lake lili mu mtengo wake komanso kusinthasintha kwake.Ma inverter a sine wave osinthidwanthawi zambiri zimakhala zotsika mtengo kuposa ma inverter a sine wave okha, zomwe zimapangitsa kuti zikhale chisankho chodziwika bwino pakati pa ogula omwe amasamala kwambiri za bajeti. Komabe, ndikofunikira kudziwa kuti si zida zonse zamagetsi zomwe zimagwirizana ndi ma inverter a sine wave osinthidwa.

Ubwino waukulu wa ma modified sine wave inverters ndi kuthekera kwawo kuyendetsa zida zosiyanasiyana. Ndi abwino kugwiritsa ntchito zida zoyambira monga mafani, magetsi, ndi zida zamagetsi. Kuphatikiza apo, amatha kuthana ndi katundu wotsutsa, kutanthauza kuti, zida zomwe zili ndi mulingo wokhazikika wa kukana, monga mababu a incandescent. Chifukwa chake ngati muli ndi makina osungira magetsi osungira pazadzidzidzi kapena maulendo okagona, modified sine wave inverter ingakhale yabwino kwambiri.

Chimodzi mwa zovuta za ma modified sine wave inverters ndikugwirizana kwawo ndi zida zamagetsi zomwe zimakhala zosavuta kugwiritsa ntchito. Zipangizo zina, monga ma laputopu, mapiritsi, ndi zida zina zachipatala, sizingagwire ntchito bwino ndipo zitha kuwonongeka zikalumikizidwa ku modified sine wave inverter. Zipangizozi zimafuna sine wave yoyera komanso yosalala kuti zigwire ntchito bwino, ndichifukwa chake pure sine wave inverter ikulimbikitsidwa pa ntchito zotere.

Kuti timvetse ukadaulo womwe uli kumbuyo kwa inverter yabwino ya sine wave, tiyeni tifufuze mozama pang'ono. Njirayi imayamba ndi gwero lamagetsi la DC, nthawi zambiri batire, lomwe limagwiritsa ntchito circuit ya pulse-width modulated (PWM). Circuit iyi imapanga mawonekedwe a mafunde a masitepe poyatsa ndi kuzima magetsi mwachangu.

Mafunde omwe amabwera chifukwa cha mafundewa amakhala ndi ma voltage okwera komanso otsika, zomwe zimapangitsa kuti pakhale mafunde a pseudo-sine. Ngakhale kuti sangakhale osalala ngati mafunde oyera a sine, amathabe kupereka mphamvu zokwanira zoyendetsera zamagetsi popanda mavuto akulu. Komabe, zida zina zamagetsi zodziwika bwino zimatha kugwedezeka kapena kutayika bwino zikalumikizidwa ku inverter yosinthidwa ya sine wave.

Opangama inverter a sine wave osinthidwanthawi zambiri mumawonjezera zida zamagetsi zina kuti muchepetse kusokonekera kwa harmonic ndikukweza mawonekedwe a mafunde. Zida izi zimapangidwa kuti zichepetse zotsatira zoyipa pazida zobisika komanso kupereka chidziwitso chabwino kwa ogwiritsa ntchito. Komabe, ndikofunikira kukumbukira kuti ngakhale ndi kusinthaku, mafunde a sine osinthidwa sadzakhala oyera komanso okhazikika ngati mafunde oyera a sine.

Mwachidule, chosinthira mafunde cha sine ndi njira yotsika mtengo komanso yosinthasintha yogwiritsira ntchito zida zamagetsi zosiyanasiyana. Chimapereka mphamvu zokwanira zoyendetsera zida zoyambira komanso katundu woletsa. Komabe, chifukwa cha mawonekedwe a mafunde a masitepe omwe chimapanga, sichingakhale choyenera kugwiritsa ntchito zamagetsi osavuta kumva. Musanasankhe pakati pa chosinthira mafunde cha sine ndi chosinthira mafunde cha sine, ndikofunikira kumvetsetsa zofunikira za chipangizocho.
