Kodi Pulse Power Supply ndi chiyani?

Pulse power supply ndi mtundu wa mphamvu zamagetsi zomwe zimagwiritsa ntchito ma pulse rectifiers kutembenuza alternating current (AC) kuti iongolere panopa (DC) molamulidwa. Ukadaulowu umagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, kuphatikiza zida zamakampani, matelefoni, ndi zida zamankhwala. M'nkhaniyi, tiwona lingaliro la mphamvu ya pulse ndikuwunika momwe ma pulse rectifiers amagwirira ntchito.

Kodi Pulse Power Supply ndi chiyani?

A pulse power supply ndi mtundu wapadera wa magetsi omwe amapereka mphamvu zamagetsi mu mawonekedwe a pulses. Ma pulse awa nthawi zambiri amakhala ngati mafunde a square kapena mafunde ena okhala ndi mawonekedwe olamulidwa. Ntchito yayikulu yamagetsi amagetsi ndikusintha voteji ya AC yomwe ikubwera kukhala yoyendetsedwa ndi DC. Njira yosinthirayi ndiyofunikira pakuwongolera zida zamagetsi ndi zida zomwe zimafunikira mphamvu yokhazikika komanso yodalirika ya DC.

Mphamvu zamagetsi zamtundu wa pulse zimadziwika chifukwa chakuchita bwino komanso kuthekera kopereka mphamvu zochulukirapo, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito pomwe magwero amagetsi ophatikizika komanso amphamvu amafunikira. Kuphatikiza apo, zida zamagetsi zamagetsi zimatha kutulutsa mafunde apamwamba kwambiri, omwe ndi opindulitsa pazogwiritsa ntchito monga ma pulsed laser systems, electromagnetic forming, komanso kuyesa kwamphamvu kwambiri kwa fizikisi.

Kodi Pulse Rectifier ndi chiyani?

Pulojekiti yosinthira kugunda ndi gawo lofunikira pamakina operekera mphamvu zamagetsi. Ili ndi udindo wosintha ma voteji a AC omwe akubwera kukhala voteji ya DC. Mosiyana ndi zokonzanso zachikhalidwe, zomwe zimatulutsa kutulutsa kwa DC kosasunthika, zowongolera ma pulse zimapanga ma pulse angapo omwe amasefedwa kuti apange kutulutsa kokhazikika kwa DC.

Kugwira ntchito kwa pulse rectifier kumaphatikizapo kugwiritsa ntchito zida za semiconductor monga diode, thyristors, kapena insulated gate bipolar transistors (IGBTs) kuti azitha kuwongolera kuyenda kwapano mudera. Posintha kayendetsedwe ka zida izi, chowongolera pulse chimatha kuumba mawonekedwe otulutsa kuti akwaniritse zofunikira za katunduyo.

Mitundu ya Pulse Rectifiers

Pali mitundu ingapo ya ma pulse rectifiers, iliyonse ili ndi mawonekedwe akeake komanso ntchito zake. Zina mwa mitundu yodziwika bwino ndi izi:

1. Single-Phase Pulse Rectifier: Chowongolera chamtunduwu chimagwiritsidwa ntchito popanga mphamvu zochepa ndipo ndichoyenera kusinthira kulowetsa kwa gawo limodzi la AC kukhala pulsating DC. Amagwiritsidwa ntchito kwambiri pamakina ang'onoang'ono amagetsi ndi makina opangira mabatire.

2. Magawo Atatu a Pulse Rectifier: Magawo atatu owongolera ma pulse amapangidwa kuti azigwira ntchito zamphamvu kwambiri ndipo amagwiritsidwa ntchito m'mafakitale pomwe mphamvu ya AC ya magawo atatu ilipo. Nthawi zambiri amagwiritsidwa ntchito poyendetsa ma mota, zida zowotcherera, komanso makina opangira makina.

3. Pulse Width Modulated (PWM) Rectifier: PWM rectifiers amagwiritsa ntchito njira yotchedwa pulse width modulation kuti athe kuwongolera mphamvu yamagetsi. Posintha m'lifupi mwake ma pulses, okonzansowa amatha kukwaniritsa kuwongolera bwino kwamagetsi komanso kuchita bwino kwambiri. Nthawi zambiri amagwiritsidwa ntchito pamagetsi apamwamba kwambiri komanso ma drive amagalimoto.

Ubwino wa Pulse Power Supply

Magetsi amtundu wa pulse amapereka maubwino angapo kuposa machitidwe opangira magetsi. Zina mwazabwino zake ndi izi:

1. Kuchita Bwino Kwambiri: Zida zamagetsi zamagetsi zimadziwika chifukwa chapamwamba kwambiri, zomwe zimapezeka pogwiritsa ntchito makina opangira ma pulse rectifiers ndi njira zowongolera. Izi zimabweretsa kuchepa kwa mphamvu zamagetsi komanso kutsika kwa ndalama zogwirira ntchito.

2. Kukula Kwapang'onopang'ono: Mphamvu zamagetsi zamagetsi zimatha kutulutsa mphamvu zambiri mu mawonekedwe ophatikizika, kuwapanga kukhala oyenera kugwiritsa ntchito pomwe malo ali ochepa.

3. Kuyankha Mwachangu: Chikhalidwe cha pulsed cha mphamvu yotulutsa mphamvu chimalola mphamvu zamagetsi kuyankha mwamsanga kusintha kwa katundu, kuwapanga kukhala abwino kwa machitidwe amphamvu monga makina a pulsed laser ndi ma drive othamanga kwambiri.

Kugwiritsa Ntchito Pulse Power Supply

Zida zamagetsi zamagetsi zimapeza ntchito m'mafakitale ndi matekinoloje osiyanasiyana. Zina mwazomwe zimagwiritsidwa ntchito ndi izi:

1. Pulsed Laser Systems: Zida zamagetsi zamagetsi zimagwiritsidwa ntchito popereka magetsi apamwamba, apamwamba kwambiri omwe amafunikira kuyendetsa makina a pulsed laser kuti akonze zinthu, njira zamankhwala, ndi kafukufuku wa sayansi.

2. Kupanga kwa Electromagnetic: Popanga zinthu monga kupanga zitsulo ndi mawonekedwe, mphamvu zamagetsi zimagwiritsidwa ntchito popereka mphamvu zamphamvu kwambiri kuti apange mphamvu yamagetsi yamagetsi yopangira zitsulo.

3. Zipangizo Zamankhwala: Zida zamagetsi zamagetsi zimagwiritsidwa ntchito pazida zamankhwala monga defibrillators, electrocautery, ndi magnetic resonance imaging (MRI) kuti apereke mphamvu yofunikira pakuwunika ndi kuchiza.

4. Industrial Automation: Mu mafakitale opanga makina ndi ma robotics, mphamvu zamagetsi zamagetsi zimagwiritsidwa ntchito kuyendetsa ma servo motors ndi ma actuators amphamvu kwambiri, kupereka kuwongolera kolondola komanso kuyankha mwachangu.

Pomaliza, makina opangira magetsi othamanga, okhala ndi ma pulse rectifiers pachimake, amatenga gawo lofunikira popereka mphamvu zokhazikika komanso zoyendetsedwa za DC pazogwiritsa ntchito zosiyanasiyana. Kuchita bwino kwawo, kukula kwake kocheperako, komanso kuyankha mwachangu zimawapangitsa kukhala oyenerera ntchito zamafakitale, zamankhwala, ndi sayansi. Pomwe ukadaulo ukupitilirabe patsogolo, magetsi amagetsi akuyembekezeka kuchita gawo lofunikira kwambiri pakuwongolera zida zamagetsi zamagetsi zogwira ntchito kwambiri komanso ma e.zida.
