Kodi Pulse Power Supply ndi chiyani?

Mphamvu ya pulse ndi mtundu wa mphamvu yomwe imagwiritsa ntchito ma pulse rectifiers kuti isinthe alternating current (AC) kukhala direct current (DC) mwanjira yolamulidwa. Ukadaulo uwu umagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, kuphatikizapo zida zamafakitale, kulumikizana, ndi zida zamankhwala. M'nkhaniyi, tifufuza lingaliro la pulse power supply ndikufufuza momwe ma pulse rectifiers amagwirira ntchito.

Kodi Pulse Power Supply ndi chiyani?

Mphamvu ya pulse ndi mtundu wapadera wa mphamvu yomwe imapereka mphamvu zamagetsi mu mawonekedwe a pulse. Ma pulse amenewa nthawi zambiri amakhala mu mawonekedwe a mafunde a sikweya kapena ma waveform ena okhala ndi mawonekedwe olamulidwa. Ntchito yayikulu ya mphamvu ya pulse ndikusintha magetsi a AC omwe akubwera kukhala mphamvu ya DC yolamulidwa. Njira yosinthira iyi ndiyofunikira pakuyendetsa zida zamagetsi ndi zida zomwe zimafuna mphamvu ya DC yokhazikika komanso yodalirika.

Mphamvu zamagetsi za pulse zimadziwika chifukwa cha kugwira ntchito bwino komanso kuthekera kwawo kupereka mphamvu zambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito komwe kumafunika magwero amphamvu ang'onoang'ono komanso olimba. Kuphatikiza apo, mphamvu zamagetsi za pulse zimatha kupereka mafunde amphamvu kwambiri, zomwe ndi zabwino pa ntchito monga makina a laser oyendetsedwa, kupanga ma electromagnetic, ndi kuyesa kwa fizikisi yamphamvu kwambiri.

Kodi Pulse Rectifier ndi chiyani?

Chosinthira mphamvu ya pulse ndi gawo lofunika kwambiri pa dongosolo lamagetsi a pulse. Chimayang'anira kusintha magetsi a AC omwe akubwera kukhala magetsi a DC othamanga. Mosiyana ndi zosinthira zachikhalidwe, zomwe zimapanga mphamvu ya DC yokhazikika, zosinthira mphamvu ya pulse zimapanga ma pulse angapo omwe amasefedwa kuti apange mphamvu ya DC yokhazikika.

Kugwira ntchito kwa pulse rectifier kumaphatikizapo kugwiritsa ntchito zipangizo za semiconductor monga ma diode, thyristors, kapena insulated gate bipolar transistors (IGBTs) kuti azitha kuyendetsa bwino magetsi mu dera. Mwa kusintha kayendedwe ka zipangizozi, pulse rectifier imatha kupanga mawonekedwe a mafunde otuluka kuti akwaniritse zofunikira za katundu.

Mitundu ya Zokonzanso Ma Pulse

Pali mitundu ingapo ya ma pulse rectifiers, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake. Mitundu ina yodziwika bwino ndi iyi:

1. Chosinthira Mphamvu ya Mpweya Chimodzi: Mtundu uwu wa chosinthira mphamvu umagwiritsidwa ntchito pa ntchito zamphamvu zochepa ndipo ndi woyenera kusintha cholowetsa cha AC cha gawo limodzi kukhala chotulutsa cha DC chothamanga. Chimagwiritsidwa ntchito kwambiri m'magetsi ang'onoang'ono komanso makina ochapira mabatire.

2. Chowongolera Mpweya Cha Magawo Atatu: Chowongolera Mpweya cha magawo atatu chapangidwa kuti chigwire mphamvu zambiri ndipo chimagwiritsidwa ntchito m'mafakitale komwe mphamvu ya AC ya magawo atatu imapezeka. Nthawi zambiri amagwiritsidwa ntchito m'magalimoto oyendetsa magalimoto, zida zowotcherera, ndi machitidwe odziyimira pawokha amakampani.

3. Pulse Width Modulated (PWM) Rectifier: Ma rectifier a PWM amagwiritsa ntchito njira yotchedwa pulse width modulation kuti azitha kuyendetsa voteji yotulutsa. Mwa kusintha m'lifupi mwa ma pulses, ma rectifier awa amatha kukwaniritsa kulamulira kwa voteji molondola komanso kugwira ntchito bwino kwambiri. Nthawi zambiri amagwiritsidwa ntchito mumagetsi amphamvu komanso ma motor drive.

Ubwino wa Pulse Power Supply

Mphamvu zamagetsi zamagetsi zimapatsa ubwino wambiri poyerekeza ndi njira zamakono zoperekera magetsi. Zina mwa zabwino zazikulu ndi izi:

1. Kugwiritsa Ntchito Bwino Kwambiri: Mphamvu zamagetsi zoyendera magetsi zimadziwika kuti zimagwira ntchito bwino kwambiri, zomwe zimachitika pogwiritsa ntchito zida zowongolera mpweya ndi njira zamakono zowongolera. Izi zimapangitsa kuti magetsi achepe komanso ndalama zogwirira ntchito zichepe.

2. Kukula Kochepa: Mphamvu zamagetsi zimatha kupereka mphamvu zambiri mu mawonekedwe ocheperako, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito komwe malo ndi ochepa.

3. Kuyankha Mwachangu: Mphamvu yamagetsi yotulutsa imalola magetsi kuti ayankhe mwachangu kusintha kwa katundu, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mosiyanasiyana monga makina a laser oyendetsedwa ndi ma drive a mota othamanga kwambiri.

Kugwiritsa Ntchito Mphamvu Yopangira Ma Pulse

Zipangizo zamagetsi zamagetsi zimapezeka m'mafakitale ndi ukadaulo wosiyanasiyana. Zina mwa ntchito zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

1. Makina a Laser Opunduka: Mphamvu zamagetsi zopunduka zimagwiritsidwa ntchito kupereka magetsi amphamvu komanso amphamvu kwambiri ofunikira kuyendetsa makina a laser opunduka kuti agwiritsidwe ntchito pokonza zinthu, njira zachipatala, komanso kafukufuku wasayansi.

2. Kupanga Magetsi: Mu njira zopangira zinthu monga kupanga ndi kupanga zitsulo, magetsi a pulse amagwiritsidwa ntchito popereka ma pulse amphamvu kwambiri kuti apange mphamvu zamagetsi zopangira zigawo zachitsulo.

3. Zipangizo Zachipatala: Mphamvu zamagetsi zimagwiritsidwa ntchito mu zipangizo zachipatala monga ma defibrillator, zipangizo zamagetsi, ndi maginito ojambulira zithunzi (MRI) kuti apereke mphamvu yofunikira pa njira zodziwira matenda ndi kuchiritsa.

4. Makina Oyendetsera Zinthu Zamakampani: Mu makina oyendetsera zinthu zamafakitale ndi maloboti, magetsi oyendera magetsi amagwiritsidwa ntchito kuyendetsa ma servo motors amphamvu kwambiri ndi ma actuator, kupereka ulamuliro wolondola komanso kuyankha mwachangu.

Pomaliza, makina opangira magetsi a pulse, omwe ali ndi ma pulse rectifiers awo pakati, amachita gawo lofunika kwambiri popereka mphamvu ya DC yokhazikika komanso yolamulidwa pa ntchito zosiyanasiyana. Kugwiritsa ntchito bwino kwawo, kukula kwake kochepa, komanso kuyankha mwachangu kumapangitsa kuti zikhale zoyenera kugwiritsa ntchito mafakitale, zamankhwala, komanso sayansi. Pamene ukadaulo ukupitilira kupita patsogolo, magetsi a pulse akuyembekezeka kukhala ndi gawo lofunika kwambiri pakupatsa mphamvu m'badwo wotsatira wa zida zamagetsi zogwira ntchito bwino komanso zamagetsi.zida.
