Ka piha-nalu rectifier, a pehea ia e hana

Rectifier kapaia uila mana converters, a he mea uholo uila 'ole' ē aʻe lolouila lima kūlana kiʻekiʻe no ka hoʻololi 'ana i AC hoʻokomo o ka mana i DC auaiaea. Wave rectifier kūkuluʻia ma luna o ka hapa-alahaka a me alahaka kaapuni, i ka piha kahua o ka a mākou e noʻonoʻo.

Ke pā like o ka manaʻo, a me ka piha-nalu rectifier

Ka hapa nui o kēia mau mea i hana i ka unidirectional ripple anakahi uila. E pahee no ka pulsation, e hoʻohana kūikawā kānana.
E hoʻoikaika rectifier kiko'î e pono ai, e hōʻike i kaʻikena pele no nā hapalua-manawa o ka hoʻokomo o anakahi uila. No kēia mea, nāʻano o nā wahi i puhi ai hoʻohana i ka hapa-nalu rectification, a hana like antiphase, a ma ka synchronism me ka pono ole, e haawe.

Me keia inclusion he pono mau iniiaiie anakahi uila kumu, a e i kekahi, he pono ole wahi. Kēia noaia ua kapaia "piha-nalu rectifier me konu wahi." Ka awelike waiwai o ke anakahi uila i loko o ka haawe resistors ma rectification ka piha-nalu o ia nā hoailona, e oi palua ka hapa-nalu huakai kaapuni.

It E e kaulana ia dvuhpolupeiodnoy manaʻo ai i ka midpoint, i kona io, ao ke ano. I ka papa ae ka kekahi diode ma ke ku pono aʻe anakahi uila piko ma ka pae kīnā i ka i kā mākou o ka palua o ka hoʻokomo o anakahi uila, mea e e hoʻomanaʻo koho diodes no ka rectifier.

Ma keia manao, noonoo i ka oi piha piha-nalu rectifier huakai kaapuni a me ka mea hiki ke hooheheeia maʻiʻo me ka nuiʻeleu like paha maloko e kū'ē'ē mai. Ua hiki aku i ke alo o ka nui pōʻino pili me ka nui hahana maoli nō kēia o ka mea hoʻololi uila.

Ma kūkulu ia i ke kaapuni me ka smoothing mea pihana, ia mea pono e noonoo i ka huahelu alternating anakahi uila mea mau i loko o ka pae'ōnaehana Hawaiʻi, a me ka nui loa nō uuku ma mua o ka mea i kā mākou ikaika hawewe. I ka wa e kaawale aku o ka haawe ana ma luna o ka mea pihana ka rectified anakahi uila ka manawa like ikaika hawewe. Kēia 'o ia hoʻi i ka piha-nalu rectifier me he hookahi-pae alternating pono o ka mea pihana 12, ka wāʻaʻohe haawe hookipa mai i ke anakahi uila o 17 V. Mai keia, ua hiki ke manao nei makou, ma lalo o haawe ana ka rectified anakahi uila emi, akā,' aʻole e lilo emi o ke anakahi uila nei aiaiiuo papa, a e e hooponoponoia ia mea, ma ka nona iho o ka smoothing mea pihana.

ua ho'ākāka 'ia ma ia rectifier kaapuni like penei. I mea e uhi i ke 'ākeʻakeʻa a me ka mea hoʻololi uila iniiaiie o Kahualoa Kokohi mea i pili i ka Kānana, i ua haku o nā capacitors me ka i pili waena wahi i ka lepo. Ka mea i koi ia unipolar, a no ka emi i ka hālāwai hope pahiki o ke anakahi uila Loipālākiō ma ia mea 200 V.

Nō kāu, ua hoonoho i ke kuapo i ka condenser, ia mea e pono ke keʻakeʻa i ka papa kuhikuhiE anakahi uila i ana i loko o ka rectifier capacitors. Fullwave rectifier mea hoʻololi uila i ke kiʻekiʻe o Kahualoa Kokohi i ka piko piula wai, akā, i loko o kēia alahaka kaapuni ia auoiaea mea i pono. Kānana no ka rectifier, a me ka mea pihana he mau moʻo mea pale mū holapū. Eia naʻe, he haahaa nui o ka ripple mea maikaʻi nō ia i hui i kekahi auoiaea mea pihana a me ka mea pale mū holapū.

No ka hana uila machines e like me ka rula o ka reversibility, anakahi uila rectifiers pu me ka mea hoʻololi i nāʻano o ka pila machines. Kapaia mea hoʻololi mea pio DC anakahi uila i AC.
