Pa mitundu ya inverter ndi zosiyana

Kutengera zosowa zanu ndi zomwe mukufuna, mutha kusankha mitundu yosiyanasiyana ya ma inverters.Izi zikuphatikiza square wave, modified square wave, ndi pure sine wave inverter.Onse amasintha mphamvu yamagetsi kuchokera kugwero la DC kukhala magetsi osinthira, omwe amagwiritsidwa ntchito ndi zida.Inverter imathanso kusinthidwa kuti ipange magetsi omwe mukufuna.

Ngati mukufuna kugula inverter yatsopano, muyenera kuwerengera kuchuluka kwa mphamvu zomwe zidagwiritsidwa ntchito pazida zanu.Mphamvu yonse ya inverter imalongosola mphamvu zomwe chipangizocho chingapereke pa katundu.Izi nthawi zambiri zimawonetsedwa mu watts kapena kilowatts.Mutha kupezanso inverter yokhala ndi chiwongolero champhamvu champhamvu kwambiri, koma izi nthawi zambiri zimakhala zodula.

Imodzi mwamitundu yofunikira kwambiri ya ma inverter, square wave inverter, imatembenuza gwero la DC kukhala lalikulu lotulutsa AC.Mafundewa ndi otsika kwambiri pamagetsi komanso apano, kupangitsa kuti ikhale yabwino kwa ogwiritsa ntchito osamva bwino.Ndiwonso mtundu wotsika mtengo wa inverter.Komabe, mawonekedwe amtunduwu amatha kupanga "kung'ung'udza" akalumikizidwa ndi zida zomvera.Siyoyenera kuyika zida zamagetsi ndi zida zina.

Mtundu wachiwiri wa inverter, mawonekedwe osinthika a square wave, amasintha gwero la DC kukhala lamakono.Ndiwothandiza kwambiri kuposa square wave, koma osati yosalala.Inverter yamtunduwu imatha kutenga mphindi zingapo kuti iyambike. Sichisankho chabwino pazida zomwe zimafunikira kuyambiranso mwachangu.Kuphatikiza apo, chinthu cha THD (kusokoneza kwathunthu kwa mafunde) kwa mafunde kumatha kukhala kokwera, zomwe zimapangitsa kuti zikhale zovuta kugwiritsa ntchito zina.Mafunde amathanso kusinthidwa kuti apange pulsed kapena modified sine wave.

Ma inverters amatha kupangidwa ndi mitundu yosiyanasiyana yamitundu yosiyanasiyana yamagetsi, iliyonse yomwe imayankha zosiyanasiyana.Ma inverters atha kugwiritsidwanso ntchito kupanga mafunde osinthidwa a sine, mafunde osunthika kapena osinthidwa masikweya, kapena mafunde oyera a sine.Mukhozanso kusankha inverter yodyetsera voteji, yomwe ili ndi mawonekedwe a buck-converter.Mitundu iyi ya ma inverters nthawi zambiri imakhala yaying'ono, yopepuka, komanso yotsika mtengo kuposa ma inverters otengera ma transformer.

Ma inverters ali ndi mwayi wogwiritsa ntchito gawo la thyristor.Dera la thyristor limayendetsedwa ndi commutation capacitor, yomwe imayang'anira kuyenda kwamakono.Izi zimathandiza kuti thyristors apereke mphamvu yaikulu yogwiritsira ntchito mphamvu.Palinso mabwalo okakamiza osinthira omwe amatha kuwonjezeredwa ku ma SCR.

Mtundu wachitatu wa inverter, multilevel inverter, imatha kupanga ma volts apamwamba a AC kuchokera pazida zotsika.Mtundu uwu wa inverter umagwiritsa ntchito mitundu yosiyanasiyana yamitundu yosiyanasiyana kuti akwaniritse zotayika zosinthika.Ikhoza kupangidwa ngati mndandanda kapena dera lofanana.Itha kugwiritsidwanso ntchito pamagetsi oyimira kuti athetse kusintha kwanthawi yayitali.

Kupatula mitundu ya ma inverters omwe tawatchulawa, mutha kugwiritsanso ntchito inverter yosinthira ma frequency motor kuti musinthe mawonekedwe ake ndikukulolani kuti musinthe ma voliyumu.Ma inverter amtunduwu amathanso kugwiritsa ntchito njira zosiyanasiyana zowongolera kuti akwaniritse bwino.de ya inverter.
