Matla-Phepelo litšobotsi

litšobotsi tse matla-phepelo

Ho na le tse 'maloa matla-phepelo litšobotsi tse lumellanang tse amang tshebetso bona:

Suthela:  The feto-dc khumo gagamalo ka mosebetsi wa nako kamehla mola gagamalo, mojaro, le mocheso ambient.

Matla ka karabelo:  phepelo matla a ka 'na ho hiriloe ka tsamaiso ea moo ho nang le tlhokahalo ea ho fana ka ho itima lijo a maholo e le karabelo ya phetoho matleng a boima. Hore e ka ba ho le joalo bakeng sa mojaro oa microprocessors phahameng-lebelo le mesebetsi matla-taolo ya. Tabeng ena, ho microprocessor ka 'na ba le boemong ba standby o le holim' a taelo ea e tlameha ho qala ho fihlela kapa tima hang-hang, eo e lefisang phahameng maqhubu a maholo ka ho itima lijo ditefello ramp ka phepelo matla. Ho amohela le microprocessor, ea phepelo ya khumo gagamalo lokela ramp hodimo kapa tlase ka hare ho e itseng nako karohano, empa ntle le overshoot ka tsela e feteletseng. 

Bokgoni:  karo-karolelano ea khumo-to-input matla (ka liphesente tse), lekanngoa ka fuoa mojaro jwale le maemo a ka lebitso mola (Pout / Pin).

Holdup nako:  Nako e leng nakong eo phepelo ea matla khumo gagamalo ntse hara ga tlhaloso e latelang ho lahleheloa ke matla a input.

Inrush jwale:  Peak instantaneous input jwale huloang ke phepelo matla e ka ba retelehelang-on.

Machaba litekanyetso tsa hae:  bolela ka ho toba ditlhoko polokeho ya phepelo ya matla le lumelleha EMI (motlakase tshitsiso) maemo. 

Ho itšehla thajana:  motlakase karohano pakeng tsa input le khumo ea phepelo matla lekanngoa ka volts. A bao e seng se ka thōko se na le dc tseleng pakeng tsa input le khumo ea phepelo, athe e ka thōko matla phepelo sebelisang e transformer ho felisa dc tseleng pakeng input le khumo.

Line molao oa tsamaiso:  Fetola ka boleng ba dc khumo gagamalo sephetho ho tswa ho fetola lenaihana input gagamalo, boletsweng e le phetoho e ± MV kapa ±%.

Mojaro molao oa tsamaiso:  Fetola ka boleng ba dc khumo gagamalo sephetho ho tswa ho fetola mojaro tloha bulehileng-oa potoloho ho palo e kahodimodimo-rated khumo jwale, boletsweng e le phetoho e ± MV kapa ±%.

Khumo lerata:  Sena se ka etsahala ka phepelo matla ka mokgwa wa eo mohloli lekgutshwanyane matla phahameng maqhubu a. Lerata e le bakoang ke lefisa le tjhajolla tsa capacitances parasitic hara phepelo matla nakong ea potoloho ea ho sebelisa mehaho ea eona. Molumo oa eona o polygonal le ka itšetleha ka mojaro impedance, filtara e ka ntle, 'me kamoo ho lekanya. 

Khumo gagamalo trima:  Most power supplies have the ability to “trim” the output voltage, whose adjustment range does not need to be large, usually about ±10%. One common usage is to compensate for the dc distribution voltage drop within the system. Trimming can either be upward or downward from the nominal setting using an external resistor or potentiometer.

Nako le nako 'me ka tšohanyetso ho kheloha (PARD): ho sa batleheng nako le nako (ripple) kapa aperiodic (lerata) kheloha ea matla-phepelo khumo gagamalo tloha boleng lona ka lebitso. PARD e bontšitsoeng ka MV tlhōrō-to-tlhōrō kapa rms, ka kgonothebolo qoolloa.

Peak jwale:  The lebetsoeng le hona joale hore phepelo matla ka fana ka nako e khutšoanyane. 

Peak matla:  The feletseng lebetsoeng le khumo matla hore phepelo matla ka hlahisa ntle ho senya. Ho ka tloaelo ho hantle ka nģ'ane ho tsoelang pele e ka tseptjoang ea bokgoni khumo matla le lokela ho feela ka sebelisoa infrequently.

Matla-phepelo hlahlamanya:  Sequential mothinya-ka le theoha thepa matla 'na ha hlokahala ho tsamaiso ea le voltages multiple ho sebelisa mehaho. Ke hore, voltages lokela ho sebediswa ka tatelano itseng, ho seng joalo ea tsamaiso ka ho senyeha. Ka mohlala, ka mor'a ho sebelisa gagamalo pele 'me e fihla boleng itseng, e gagamalo bobeli ka ramped,' me joalo-joalo. Hlahlamanya sebetsa ka khutlisetsang ha matla e tlosoa, le hoja lebelo ha se hangata e le karolo e khōlō ea bothata ka retelehelang ho-on.

Ka thōko ka / theoha:  ena e ratang fetang fapoha ho retelehela a fanang ka matla ka le theoha. Matla-phepelo ya data-lakane tobileng hangata qaqileng entsprechen dc bakeng sa tse hōle ka / theoha, thathamisa le ho theoha maemo mabaka hlokahala.

Thōko kutloisiso e:  A tloaelehileng matla phepelo basekaseki khumo lona gagamalo le fepa karolo e itseng ea ho khutlela phepelo ho fana gagamalo molao oa tsamaiso. Ka tsela ena, ha khumo le atisa ho tsoha kapa oa, ditshwaelo tsa ho o laola ka phepelo ea khumo gagamalo. Leha ho le joalo, ho lula re ena le khumo ka nako eohle ke mojaro, e leng phepelo ea matla a lokela ho ha e le hantle hlokomela gagamalo ka mojaro oa ka. Empa, dikgokelo tloha khumo le phepelo e le matla a ho mojaro oa eona na ho hanyetsa le hona joale e phallang ka bona hore hlahisa gagamalo lerotholi hore baka gagamalo phapang pakeng tsa khumo le phepelo e le mojaro oa sebele. Bakeng sa molao oa tsamaiso homolog, ho gagamalo fepa khutlela phepelo matla e lokela ho ba ea sebele mojaro gagamalo. Phepelo ya tse peli (mmoho le ho tloswa) thōko dikgokelo kutloisiso e hlokomela sebele mojaro gagamalo, karolo e itseng ea eona e ka nako eo a fepa khutlela phepelo ka gagamalo lerotholi fokolang haholo hobane hona joale ka dikgokelo tse peli tse ka thōko le kutloisiso ea se tlaase haholo. Ka lebaka leo, ho gagamalo sebelisoa ho mojaro ho e laolwa.

Ripple:  Rectifying le filtara e sephetho le switjha matla phepelo ea khumo ka lenaihana motsoako (ripple) hore palama ka dc khumo lona. Ripple maqhubu ke a mang a mangata ea bohlokoa ea ho converter o switjha maqhubu a, e leng itšetlehile ka topology converter. Ripple ke batlang angoe ke mojaro jwale, empa ka fokotseha ka filtara Link capacitor.

Tracking:  Ha ho sebelisa thepa e multiple matla khumo oo ka oona outputs le 'ngoe kapa ho feta latela e' ngoe le liphetoho tse ka line, mojaro, le mocheso, e le hore e mong le e lula e tšoanang tekanyo e lekanang ya khumo gagamalo, ka hare ho boletsweng latedisa mamello, mabapi le ho boleng ba tloaelehileng.
