Power Supply-Halaye

ikon-wadata halaye

Akwai da dama ikon-wadata halaye da cewa ya shafi aiki:

Gantali:  The bambancin a dc fitarwa ƙarfin lantarki a matsayin aiki na lokaci a m line ƙarfin lantarki, aza, kuma na yanayi zafi.

Dynamic amsa:  A ikon samar iya aiki a cikin wani tsarin inda akwai wani da ake bukata don samar da sauri tsauri mayar da martani ga wani canji a load iko. Wannan zai iya zama haka al'amarin ga kaya na high-gudun microprocessors da ikon-management ayyuka. A wannan yanayin, da microprocessor iya zama a cikin wata jiran aiki jihar, kuma a kan umurnin da shi dole ne a fara up ko kashe nan da nan, wanda ya dora high tsauri igiyoyin da sauri gangara rates a kan samar da wutar lantarki. Don saukar da da microprocessor, da wadata da ta fitarwa ƙarfin lantarki dole gangara sama ko ƙasa a cikin kayyade lokaci tazara, amma ba tare da wuce kima overshoot. 

Yadda ya dace:  rabo na fitarwa-to-shigar da ikon (a cikin kashi), auna a ba load halin yanzu tare da maras muhimmanci line yanayi (Pout / Fil).

Holdup lokaci:  Lokaci a lokacin da wani wutar lantarki ta fitarwa ƙarfin lantarki da har yanzu cikin jaddadawa wadannan asarar shigar da iko.

Inrush halin yanzu:  ganiya instantaneous shigar halin yanzu kõma da wani wutar lantarki a nuna-on.

International nagartacce:  Saka a samar da wutar lantarki ta aminci da bukatun da kuma canja EMI (electromagnetic tsangwama) matakan. 

Kadaici:  Banana rabuwa tsakanin shigar da fitarwa na wani ikon samar auna a volts. A ba-ya zama ruwan dare yana da wani dc hanya tsakanin shigar da fitarwa na wadata, alhãli kuwa wani ya zama ruwan dare ikon samar da ma'aikata a gidan wuta ya kawar da dc hanya tsakanin shigar da fitarwa.

Layin tsari:  Change a darajar dc fitarwa ƙarfin lantarki sakamakon wani canji a ac shigar da ƙarfin lantarki, a kayyade a matsayin canji a ± mv ko ±%.

Load tsari:  Change a darajar dc fitarwa ƙarfin lantarki sakamakon wani canji a load daga bude-rangadi zuwa iyakar-rated fitarwa halin yanzu, kayyade matsayin canji a ± mv ko ±%.

Fitarwa amo:  Wannan na iya faruwa a cikin wutar lantarki a cikin nau'i na gajeren bursts na high mita makamashi. A amo ne ya sa ta caji da dakatar da na parasitic capacitances a cikin wutar lantarki a lokacin da aiki sake zagayowar. Its mawadãta ne m, kuma za a iya dogara ne a kan kaya impedance, waje tacewa, da kuma yadda shi ne ji. 

Fitarwa ƙarfin lantarki datsa:  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.

Lokaci-lokaci da kuma bazuwar sabawa (PARD): wašanda ba'aso lokaci-lokaci (ripple) ko aperiodic (amo) sabawa da ikon-wadata fitarwa ƙarfin lantarki daga ta maras muhimmanci darajar. PARD da aka bayyana a cikin mv ganiya-to-ganiya ko rms, a wani ajali bandwidth.

Ganiya halin yanzu:  A kalla halin yanzu da cewa a samar da wutar lantarki zai iya samar for taƙaitaccen lokaci. 

Ganiya ikon:  The cikakkar iyakar fitarwa ikon cewa a samar da wutar lantarki za a iya nuna ba tare da lalacewa. Shi ne yawanci kyau fiye da ci gaba da dogara da fitarwa ikon iyawa, kuma ya kamata ne kawai a yi amfani da infrequently.

Power-wadata jerawa:  bi da bi nuna-a kuma kashe na ikon kayayyaki iya da ake bukata a tsarin da mahara aiki voltages. Wannan shi ne, voltages dole ne a yi amfani a cikin wani takamaiman tsari, in ba haka ba da tsarin za a iya lalace. Alal misali, bayan da ake ji da farko irin ƙarfin lantarki da kuma shi ya kai wani takamaiman darajar, a karo na biyu ƙarfin lantarki za a iya ramped up, da sauransu. Jerawa aiki a baya a lokacin da ikon da aka cire, ko da yake gudun ba kullum kamar yadda da yawa daga mai matsala kamar yadda bi da bi-on.

M / kashe:  Wannan an fi son a kan sauya juya ikon kayayyaki da a kashe. Power-wadata data-takardar bayani dalla-dalla yawanci daki-daki dc sigogi ga m on / off, listing da a kuma kashe dabaru matakan da ake bukata.

M ma'ana:  A hankula samar da wutar lantarki na sa ido ta fitarwa ƙarfin lantarki da kuma ciyar da wani yanki na mayar da ita ga wadata don samar da irin ƙarfin lantarki tsari. A wannan hanya, idan fitarwa o ƙarin tashi ko fada, da feedback shirya wadata ta fitarwa ƙarfin lantarki. Duk da haka, don kula da akai fitarwa a load, da ikon samar da ya kamata a zahiri saka idanu da ƙarfin lantarki a load. Amma, sadarwa daga samar da wutar lantarki ta fitarwa zuwa kãyansa da juriya da kuma na yanzu sunã gudãna su da cewa samar da wani irin ƙarfin lantarki drop cewa Halicci irin ƙarfin lantarki bambanci tsakanin wadata ta fitarwa da kuma da ainihin load. Domin mafi kyau duka tsari, da irin ƙarfin lantarki ciyar da baya ga samar da wutar lantarki ya zama ainihin kaya irin ƙarfin lantarki. Da wadata ta biyu (da kuma debe) m ji sadarwa saka idanu da ainihin kaya irin ƙarfin lantarki, da wani yanki daga abin da aka sa'an nan ciyar da baya ga samar da sosai kadan ƙarfin lantarki drop saboda halin yanzu ta hanyar biyu m ji sadarwa ne ragu. A sakamakon, da irin ƙarfin lantarki amfani da kaya da aka kayyade.

Ripple:  gyara da kuma tace a sharuddan sauyawa samar da wutar lantarki ta fitarwa sakamakon a wani ac bangaren (ripple) cewa tafiye-tafiye a kan ta dc fitarwa. Ripple mita ne wasu mahara na game da Converter ta sharuddan sauyawa mita, wanda ya dogara a kan Converter topology. Ripple ne in mun gwada unaffected ta kaya halin yanzu, amma za a iya rage ta waje capacitor tacewa.

Tracking:  Lokacin amfani da mahara fitarwa ikon kayayyaki inda daya ko fiye jimloli bi da juna da canje-canje a cikin line, kaya, da kuma yawan zafin jiki, sabõda haka, kowace kula guda gwargwado fitarwa ƙarfin lantarki, a cikin kayyade tracking haƙuri, game da na kowa darajar.
