Chii chinonzi Pulse Power Supply?

Simba repulse imhando yesimba rinoshandisa ma "pulse rectifiers" kushandura "alternating current" (AC) kuita "direct current" (DC) nenzira inodzorwa. Iyi tekinoroji inoshandiswa zvakanyanya mumabasa akasiyana-siyana, kusanganisira michina yeindasitiri, kutaurirana, uye zvishandiso zvekurapa. Muchinyorwa chino, tichaongorora pfungwa ye "pulse power supply" uye tichaongorora mashandiro e "pulse rectifiers".

Chii chinonzi Pulse Power Supply?

Simba remagetsi rinopa simba remagetsi nenzira yemapulse. Mapulse aya anowanzova mafungu akaenzana kana mamwe mafungu ane hunhu hwakarongwa. Basa guru resimba remagetsi rinopa simba nderekushandura voltage yeAC iri kuuya kuita DC inodzorwa. Maitiro aya ekushandura akakosha pakupa simba michina yemagetsi nemidziyo inoda simba remagetsi rakasimba uye rakavimbika.

Simba remagetsi epulse rinozivikanwa nekushanda zvakanaka uye kugona kwaro kupa simba rakawanda, zvichiita kuti rikwanise kushandiswa uko kunodiwa manyuko emagetsi madiki uye akasimba. Pamusoro pezvo, simba remagetsi epulse rinokwanisa kupa mafungu emagetsi akakwirira, izvo zvinobatsira kune zvishandiso zvakaita semasisitimu elaser akasimba, kugadzira electromagnetic, uye kuyedza fizikisi ine simba rakawanda.

Chii chinonzi Pulse Rectifier?

Chinogadzirisa mapuroteni chinhu chakakosha muhurongwa hwemagetsi epulse. Chine basa rekushandura voltage yeAC iri kuuya kuita voltage yeDC inoputika. Kusiyana nezvinoshandiswa pakugadzirisa mapuroteni, izvo zvinoburitsa DC inobuda zvakanaka, zvinogadzirisa mapuroteni zvinogadzira mapuroteni akawanda anozoseferwa kuti abudise DC inobuda zvakanaka.

Kushanda kwe pulse rectifier kunosanganisira kushandiswa kwe semiconductor devices dzakadai se diodes, thyristors, kana insulated gate bipolar transistors (IGBTs) kudzora kufamba kwe current mu circuit. Nekugadzirisa conduction ye devices idzi, pulse rectifier inogona kugadzira output waveform kuti ienderane nezvinodiwa zve load.

Mhando dzePulse Rectifiers

Kune mhando dzakasiyana dzezvinogadzirisa pulse, imwe neimwe ine hunhu hwayo hwakasiyana uye mashandisirwo ayo. Dzimwe dzemhando dzakajairika dzinosanganisira:

1. Single-Phase Pulse Rectifier: Rudzi urwu rwerectifier runoshandiswa pakushandisa simba shoma uye rwakakodzera kushandura single-phase AC input kuita pulsating DC output. Inowanzoshandiswa mumagetsi madiki uye masisitimu ekuchaja mabhatiri.

2. Three-Phase Pulse Rectifier: Three-phase pulse rectifiers dzakagadzirirwa kubata masimba akakwira uye dzinoshandiswa mumaindasitiri uko simba reAC remadanho matatu riripo. Dzinowanzo shandiswa mumamotor drives, mumidziyo yekuwelding, uye mumaindasitiri e automation systems.

3. Pulse Width Modulated (PWM) Rectifier: MaPWM rectifier anoshandisa nzira inonzi pulse width modulation kudzora voltage inobuda. Nekugadzirisa upamhi hwemapulses, ma rectifier aya anogona kuwana voltage chaiyo uye kushanda zvakanaka. Anowanzo shandiswa mumagetsi anoshanda zvakanyanya uye mumota.

Mabhenefiti ePulse Power Supply

Simba remagetsi rinoshandisa pulse rine zvakanakira zvakawanda kupfuura masisitimu emagetsi echinyakare. Mamwe emabhenefiti akakosha anosanganisira:

1. Kushanda Nesimba Kwazvo: Masimba emagetsi epulse anozivikanwa nekushanda kwawo kwepamusoro, izvo zvinowanikwa kuburikidza nekushandisa ma "pulse rectifiers" uye matekiniki epamusoro ekudzora. Izvi zvinoderedza kurasikirwa kwemagetsi uye kuderedza mari yekushandisa.

2. Hukuru Hwakabatana: Simba remagetsi rinoshandisa pulse rinogona kupa simba rakawanda muchimiro chakabatana, zvichiita kuti rikwanise kushandiswa munzvimbo dzisina nzvimbo yakawanda.

3. Kukurumidza Kupindura: Hunhu hwesimba remagetsi anobuda hunoita kuti magetsi emagetsi ashande nekukurumidza kana zvinhu zvichichinja mutoro, zvichiita kuti zvive zvakanaka pakushandisa zvinhu zvinoshanduka zvakaita semasisitimu elaser anofambiswa nemagetsi uye madhiraivha emota anomhanyisa kumhanya.

Mashandisirwo ePulse Power Supply

Simba remagetsi rinoshandisa pulse rinowana mashandisirwo akasiyana-siyana mumaindasitiri nematekinoroji. Mamwe emashandisirwo akajairika anosanganisira:

1. Masisitimu eLaser Anopukutwa: Simba remapukutwa rinoshandiswa kupa mapulse ane simba guru, anodiwa kuti afambise masisitimu eLaser anopukutwa pakugadzirisa zvinhu, maitiro ekurapa, uye kutsvagurudza kwesainzi.

2. Kugadzira Magetsi: Mumabasa ekugadzira akadai sekugadzira nekugadzira simbi, magetsi epulse anoshandiswa kupa simba guru rekugadzira masimba emagetsi ekugadzira zvikamu zvesimbi.

3. Midziyo Yekurapa: Simba remapulse rinoshandiswa mumidziyo yekurapa yakadai se defibrillators, electrocautery devices, uye magnetic resonance imaging (MRI) systems kuti ipe simba rinodiwa pakuongorora nekurapa.

4. Kuzvigadzira Kwemagetsi Mumaindasitiri: Muzvishandiso zvemaindasitiri nemarobhoti, magetsi epulse anoshandiswa kufambisa mamota eservo ane simba guru uye maactuator, zvichipa kutonga kwakarurama uye mhinduro nekukurumidza.

Mukupedzisa, masisitimu emagetsi epulse, ane ma "pulse rectifiers" ari pakati, anoita basa rakakosha mukupa simba reDC rakasimba uye rinodzorwa kune akasiyana mashandisirwo. Kushanda kwavo zvakanaka, saizi yavo diki, uye mhinduro nekukurumidza zvinoita kuti vakwanise kushandiswa zvakanyanya mumaindasitiri, zvokurapa, uye sainzi. Sezvo tekinoroji ichiramba ichifambira mberi, magetsi epulse anotarisirwa kutamba basa rakakosha mukupa simba kuchizvarwa chinotevera chemidziyo yemagetsi inoshanda zvakanyanya uye e-e.zvishandiso.
