Pa mitundu ya inverter ndi kusiyana kwake

Kutengera zosowa zanu ndi zosowa zanu, mutha kusankha mitundu yosiyanasiyana ya ma inverter. Izi zikuphatikizapo square wave, modified square wave, ndi pure sine wave inverter. Zonsezi zimasintha mphamvu yamagetsi kuchokera ku DC source kukhala alternating current, yomwe imagwiritsidwa ntchito ndi zida zamagetsi. Inverter imathanso kusinthidwa kuti ipange voltage yomwe mukufuna.

Ngati mukufuna kugula inverter yatsopano, muyenera kuwerengera mphamvu yonse yomwe zipangizo zanu zimagwiritsira ntchito. Mphamvu yonse ya inverter imafotokoza kuchuluka kwa mphamvu yomwe chipangizocho chingapereke pa katunduyo. Izi nthawi zambiri zimafotokozedwa mu ma watts kapena ma kilowatts. Muthanso kupeza inverter yokhala ndi mphamvu yayikulu, koma nthawi zambiri imakhala yokwera mtengo.

Chimodzi mwa mitundu yofunikira kwambiri ya ma inverter, square wave inverter, chimasintha gwero la DC kukhala square wave AC output. Mafunde awa ndi otsika mu voltage ndi current, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito ma low sensitivity. Ndi mtundu wa inverter wotsika mtengo kwambiri. Komabe, mafunde awa amatha kupanga phokoso la "humming" akalumikizidwa ku zida zamawu. Silibwino kugwiritsa ntchito zamagetsi ndi zida zina.

Mtundu wachiwiri wa inverter, womwe ndi modified square wave, umasintha gwero la DC kukhala alternating current. Ndiwothandiza kwambiri kuposa square wave, koma osati wosalala kwambiri. Mtundu uwu wa inverter ungatenge mphindi zingapo kuti uyambe kugwira ntchito. Si chisankho chabwino kwa zipangizo zomwe zimafuna kuyatsidwa mwachangu. Kuphatikiza apo, THD factor (total harmonic distortion) ya mafunde ikhoza kukhala yokwera kwambiri, zomwe zimapangitsa kuti zikhale zovuta pa ntchito zina. Mafunde amathanso kusinthidwa kuti apange pulsed kapena modified sine wave.

Ma inverter amatha kupangidwa ndi mitundu yosiyanasiyana ya ma power circuit topology, omwe amathetsa mavuto osiyanasiyana. Ma inverter amathanso kugwiritsidwa ntchito popanga ma modified sine waves, pulsed kapena modified square waves, kapena ma pure sine waves. Muthanso kusankha inverter yodzaza ndi magetsi, yomwe ili ndi mawonekedwe a buck-converter. Mitundu iyi ya ma inverter nthawi zambiri imakhala yaying'ono, yopepuka, komanso yotsika mtengo kuposa ma inverter okhala ndi transformer.

Ma inverter alinso ndi mwayi wogwiritsa ntchito thyristor circuit. thyristor circuit imayang'aniridwa ndi commutation capacitor, yomwe imayang'anira kayendedwe ka mphamvu. Izi zimathandiza kuti thyristors ipereke mphamvu yayikulu yogwiritsira ntchito mphamvu. Palinso ma forced commutation circuits omwe angawonjezedwe ku ma SCR.

Mtundu wachitatu wa inverter, multilevel inverter, ukhoza kupanga magetsi ambiri a AC kuchokera ku zipangizo zotsika mtengo. Mtundu uwu wa inverter umagwiritsa ntchito mitundu yosiyanasiyana ya ma circuit topologies kuti akonze kutayika kwa switching. Itha kupangidwa ngati sequence yotsatizana kapena parallel. Itha kugwiritsidwanso ntchito mu standby power supply kuti ichotse transient switchover.

Kupatula mitundu ya ma inverter omwe atchulidwa pamwambapa, mutha kugwiritsanso ntchito inverter yowongolera ma frequency motor kuti muwongolere mawonekedwe a mafunde ndikukulolani kusintha mphamvu yotulutsa. Mtundu uwu wa inverter ungagwiritsenso ntchito njira zosiyanasiyana zowongolera kuti uwonjezere efficiency ya inverter.de.
