Magetsi oyendetsa magetsi a inverter ndi osavuta kupanga kutentha kwambiri pansi pavuto lalikulu, mkulu panopa ndi mkulu pafupipafupi, kuphatikiza pakuchita zoziziritsira zoyenera (monga kulamulira kutentha kwa chipinda, kuwonjezera madzi otentha, ndi zina.) , komanso ayenera kukhala ndi dera loteteza kutentha kwambiri.

Momwe mungatetezere dera la inverter kuti lisatenthedwe

Zida zodzitetezera ku kutentha kwambiri ndizomwe zimatenthetsa, kusintha kwa kutentha ndi fuse kutentha. Ma thermitors a NTC nthawi zambiri amagwiritsidwa ntchito popanga magetsi kuti atetezere kutentha kwambiri, chifukwa cha kuthekera kwake kuletsa kuthamanga kwakali pano komanso kukana wamba, koma pa kukana kwa kugwiritsira ntchito mphamvu kungathe kuchepetsedwa ndi maulendo angapo mpaka mazana.

Njira zazikulu zochepetsera kusokoneza kwakunja kwa magetsi a inverter ndi awa:

Pofuna kuchepetsa kusokoneza kwakunja chifukwa cha mphamvu ya inverter, pali njira zitatu: kupanga inverter mphamvu yokha kutumiza chizindikiro chosokoneza pang'ono momwe ndingathere, kupititsa patsogolo mphamvu yotsutsa kusokoneza kwa chinthu chomwe chikusokonezedwa, ndi kugwiritsa ntchito njira zodzipatula, chizindikiro chosokoneza chomwe chimaperekedwa ndi inverter ku chinthu chosokoneza chimafooka.

Chifukwa magetsi osinthira mu inverter amagwiritsa ntchito masiwichi othamanga kwambiri kuti apange mawonekedwe owoneka bwino komanso chizindikiro chowongolera cha SPWM., chizindikiro cha pulse chokhala ndi m'mphepete chakuthwa chidzatulutsa kusokoneza kwamphamvu kwamagetsi, makamaka zotsatira zapano, adzapereka mphamvu zawo m’njira zosiyanasiyana, kusokoneza zida zina ndikupitirira kwambiri malire a Electromagnetic compatibility standards.

Choncho, opanga ma frequency converter kuti ogwiritsa ntchito apange zida zapadera zochepetsera kusokoneza kwamagetsi kopangidwa ndi inverter., kuti akwaniritse miyezo yoyendera bwino ndikuwonetsetsa kuti zida zikuyenda bwino.
