Kenyelletso ea Sehlahisoa
1.Voltage e tsitsitse phepelo ea motlakase.
Motlakase o tsitsitseng oa motlakase (phepelo ea motlakase o tsitsitseng) ke sesebelisoa sa elektroniki se ka fanang ka matla a tsitsitseng a AC kapa a DC ho mojaro, ho kenyeletsoa phepelo ea motlakase o tsitsitseng oa AC le phepelo ea motlakase e tsitsitseng ea DC ka mekhahlelo e 'meli.
2. Tlhokahalo ea ho sebelisa lisebelisoa tsa motlakase tse laoloang.
Ka tsoelopele e potlakileng ea sechaba, lisebelisoa tse sebelisang motlakase li ntse li eketseha letsatsi le letsatsi.Leha ho le joalo, tsoelo-pele ea botsofali le e saletseng morao ea lisebelisoa tsa phetisetso le kabo ea motlakase, hammoho le moralo o fosahetseng le phepelo e sa lekaneng ea motlakase li etsa hore motlakase oa basebelisi ba ho qetela o be tlase haholo, athe basebelisi ba likhoele hangata ba le matla a phahameng.Bakeng sa lisebelisoa tse sebelisang matla, haholo-holo lisebelisoa tsa theknoloji e phahameng le tse nepahetseng tse nang le litlhoko tse thata tsa motlakase, ho tšoana leha eka ha li na inshorense.
Li-voltage tse sa tsitsang li ka baka likotsi tse bolaeang kapa ho se sebetse hantle ho lisebelisoa, ho ama tlhahiso, ho baka tieho ea ho fana, boleng bo sa tsitsang, le litahlehelo tse ling tse ngata.Ka nako e ts'oanang, e potlakisa botsofali ba lisebelisoa, e ama bophelo ba eona ba tšebeletso, esita le ho chesa lisebelisoa, e le hore mong'a lona a tobane le bothata ba ho hloka ho lokisoa kapa ho tlameha ho nchafatsa thepa ka nako e khutšoanyane, e senyang lisebelisoa;maemong a tebileng, likotsi tsa polokeho li bile li etsahala, tse bakang tahlehelo e ke keng ea lekanngoa.
3. DC e laola phepelo ea motlakase.
E boetse e tsejoa e le DC voltage regulator.Matla a eona a phepelo hangata ke motlakase oa AC, ha motlakase oa motlakase oa phepelo ea AC kapa khatello ea phallo ea phallo e fetoha, motlakase o tsoang ka kotloloho oa molaoli o ka bolokoa o tsitsitse.Litekanyetso tsa motlakase oa motlakase ke botsitso ba voltage, ripple coefficient, le lebelo la karabo.Ea pele e bonts'a phello ea phetoho ea motlakase oa motlakase ho motlakase oa tlhahiso.Coefficient ea ripple e bontša boholo ba karolo ea AC ea motlakase o hlahisoang tlas'a maemo a sebetsang a lekantsoeng;ea ho qetela e bontša nako e hlokahalang bakeng sa hore motlakase o khutlele boleng ba oona bo tloaelehileng ha motlakase o kenang kapa mojaro o fetoha haholo.DC voltage regulator e arotsoe ka mekhahlelo e 'meli: e tsoelang pele conductive le switching mofuta.Ea pele ka frequency transformer ho ea mokhahlelo o le mong kapa oa mekhahlelo e meraro ea AC ho boleng bo nepahetseng, ebe oa lokisoa, oa tlhotloa, ho fumana matla a DC a sa tsitsang, ebe ka potoloho ea motlakase oa motlakase ho fumana motlakase o tsitsitseng (kapa oa hajoale).Mofuta ona oa mohala oa phepelo ea motlakase o bonolo, o ripple o nyane, ho kena-kenana le batho ka bobeli ho nyane, empa molumo o moholo, lisebelisoa tse ka sebelisoang li ngata, 'me katleho e tlase (hangata e ka tlase ho 40% ho isa ho 60%).Ea morao-rao e laola motlakase oa tlhahiso ka ho fetola karo-karolelano ea nako ea ho tima / ho tima ea ntho e lokisang (kapa switjha) ho fihlela taolo ea motlakase.Mofuta ona oa phepelo ea motlakase o sebelisa matla a manyane mme o sebetsa hantle hoo e ka bang 85%.
Sesebelisoa sa taolo ea motlakase oa 4.DC.
DC voltage regulator e sebelisoa haholo ts'ireletso ea naha, lipatlisiso tsa mahlale, liunivesithi le likoleche, lilaboratori, likhoebo tsa indasteri le tsa meepo, electrolysis, electroplating, lisebelisoa tsa ho tjhaja, le phepelo e meng ea motlakase ea DC.
Tlhaloso: LM5010A
The LM5010Ax step-down switching regulator ke mofuta o ntlafalitsoeng oa LM5010 mme sebaka sa ts'ebetso sa ho kenya se atolositsoe ho bonyane ba 6-V.LM5010Ax e fana ka mesebetsi eohle e hlokahalang ho kenya ts'ebetsong molaoli oa theko e tlase, o sebetsang hantle, o khonang ho fana ka thepa e fetang 1-A ea hona joale.Taolo ena ea matla a phahameng e kopanya N-Channel Buck Switch, 'me e fumaneha ka har'a liphutheloana tsa WSON tsa 10-pin le 14-pin HTSSOP tse ntlafalitsoeng ka mocheso.Sekema sa kamehla sa taolo ea nako ea ON-time ha se hloke matšeliso a loop a fellang ka karabelo ea nakoana ea mojaro le ts'ebetsong e nolofalitsoeng ea potoloho.Maqhubu a ts'ebetso a lula a tšoana le mela le meroalo e fapaneng ka lebaka la kamano e fapaneng pakeng tsa motlakase oa ho kenya letsoho le ON-time.Ho bona moeli oa hona joale oa phula e behiloe ho 1.25 A. Lintlha tse ling li kenyelletsa: VCC undervoltage lockout, thermal shutdown, gate drive undervoltage lockout, le maximum duty cycle limiter.
