ʻOkoʻa ma waena o hoʻokahi-phase inverter a me ʻekolu-phase inverter

1. Hoʻokahi-phase inverter

Hoʻololi ka mea hoʻohuli hoʻokahi-phase i kahi hoʻokomo DC i kahi puka puka hoʻokahi.Hoʻokahi wale nō mahele o ka volta puka / ʻā o ka inverter hoʻokahi-phase, a ʻo kona alapine nominal he 50HZ a i ʻole 60Hz nominal voltage.Ua wehewehe ʻia ka volta nominal e like me ke kiʻekiʻe o ka voltage kahi e hana ai kahi ʻōnaehana uila.Loaʻa nā voltase inoa like ʻole, ʻo ia hoʻi 120V, 220V, 440V, 690V, 3.3KV, 6.6KV, 11kV, 33kV, 66kV, 132kV, 220kV, 400kV, a me 765kV no kēia mau helu , ʻO ia ka 11kV, 22kV, 66kV, etc.?

Hiki ke hoʻokō pololei ʻia nā voltage nominal haʻahaʻa ma o ka inverter me ka hoʻohana ʻana i kahi transformer kūloko a i ʻole kaʻapuni hoʻonui i ka piʻi ʻana, ʻoiai no nā volt nominal kiʻekiʻe e hoʻohana ʻia kahi transformer booster waho.

Hoʻohana ʻia nā mea hoʻohuli hoʻokahi no nā haʻahaʻa haʻahaʻa.Ke hoʻohālikelike ʻia me ka inverter ʻekolu, ʻoi aku ka nui o ka poho hoʻokahi a ʻoi aku ka haʻahaʻa.No laila, makemake ʻia nā inverters ʻekolu no nā ukana kiʻekiʻe.

2. ʻEkolu-phase inverter

Hoʻololi nā mea hoʻohuli ʻekolu i ka DC i ʻekolu mau mana.Hāʻawi ka mana mana ʻekolu ʻekolu i kēia manawa me nā kihi ʻāpana like ʻole.ʻO nā nalu ʻekolu i hana ʻia ma ka hopena hoʻopuka ua like ka amplitude a me ke alapine, akā ʻokoʻa iki ma muli o ke kaumaha, ʻoiai ʻo kēlā me kēia nalu he 120o ka hoʻololi ʻana ma waena o kekahi.

Basically, hoʻokahi ekolu-phase inverter he 3 hoʻokahi-phase inverters, kahi o kēlā me kēia inverter he 120 degere ma waho o ka pae, a me kēlā me kēia mea hoʻohuli hoʻokahi-phase ua hoʻopili ʻia i kekahi o ʻekolu mau pahu ukana.

Nānā Maʻiʻo: He aha ka inverter ʻekolu-phase, he aha ke kuleana

Aia nā topologies ʻokoʻa no ke kūkulu ʻana i nā kaapuni inverter voltage ʻekolu.Inā he alahaka inverter, e holo ana i ke kuapo ma 120 degere mode ka hana o ka ekolu-phase inverter hana kela kuapo hana no ka huina manawa o T/6, i produces he puka hawewe me 6 kapuai.Aia kahi ʻanuʻu uila ʻaʻohe ma waena o nā pae uila maikaʻi a maikaʻi ʻole o ka nalu huinaha.

Hiki ke hoʻonui hou ʻia ka helu mana inverter.I mea e kūkulu ai i ka mea hoʻohuli me ka mana kiʻekiʻe, 2 inverters (ʻekolu-phase inverters) i hoʻopili ʻia i ka moʻo e loaʻa ai ka helu voli kiʻekiʻe.No nā helu kiʻekiʻe o kēia manawa, hiki ke hoʻopili ʻia nā 2 6-step 3 inverters.
