Perjungimas galia modulis DC smulkinimas
Trumpas Įvadas
Perjungimas galia šaltiniai gali būti padalinta į du kategorijas: AC/DC ir DC/DC. DC/DC konverteriai turi dabar pasiekė modulizacija, ir the design technology and production process have been brande and standardized both domesticly and international, and have been recognized by users. Tačiau, the modularization of AC/DC, due to its own characteristics, encounters more complex technical and manufacturing problems in the procesas iš moduliavimas.

(1) Buck circuit - a buck chopper with an average output voltage Uo less than the input voltage Ui and the same polarity.
(2) Boost circuit - boost chopper, with an average output voltage Uo greater than the input voltage Ui and the same poliškumo.
(3) Buck Boost circuit - a buck or boost chopper with an average output voltage Uo greater than or less than the input voltage Ui, opposite polarity, and inductive transmission.
(4) Cuk circuit - a buck or boost chopper with an output average voltage Uo greater than or less than the input voltage UI, opposite poliškumo, kondensatoriaus perdavimo.
AC/DC conversion is the process of converting AC to DC, and the power flow direction can be bidirectional. The power flow from the power source to the load is called "rectification", and the power flow from the load to the power source is called "active inverter". The AC/DC converter input is 50/60Hz AC power. Due to the need for rectification and filtering, relatively large filter capacitors are essential. At the same time, due to safety standards (such as UL, CCEE, etc.) and limitations of EMC directives (such as IEC, FCC, CSA), EMC filtering and the use of components that meet safety standards must be added to the AC input side, which limits the miniaturization of the AC/DC power supply volume. Additionally, due to internal high-frequency, high-voltage The action of high current switches increases the difficulty of solving EMC electromagnetic compatibility problems, which puts forward high requirements for the design of internal high-density installation circuits. Due to the same reasons, high voltage and high current switches increase power consumption and limit the modularization process of AC/DC converters. Therefore, it is necessary to adopt power system optimization design methods to achieve a certain degree of satisfaction in its work efficiency.
AC/DC konversija gali būti padalinta į pusė banga grandinė ir pilna banga grandinė pagal į į laidus metodą iš the circuit. Pagal į skaičių iš galios fazių, it gali būti padalinta į į vienfazę, trifazę, ir daugiafazę. Pagal į the working quadrant of the circuit, it can be divided into on one quadrant, two quadrants, three quadrants, three quadrants, and four quadrants.
Paprastas dizainas. Jūs tik reikia vienas galia modulis su a mažu skaičiumi iš diskrečių komponentų į gauti galia.
Shorten the development cycle. Modular power supplies are generally available with multiple input and output options. Users can also repeatly stack or cross stack to form a modular combination power supply, achieving multiple inputs and outputs, greatly reduceing prototype development time.
Žemi techniniai reikalavimai. Moduliniai galia šaltiniai are paprastai įrengti su standartizuotais front-end, labai integruotais galia moduliais, ir kiti komponentai, gamyba galia tiekimas dizainas paprastesnis.
The module power supply casing has a structure that integrates heat sink, heat sink, and casing, achieving a laidus cooling method for the module power supply, making the temperature value of the power supply close to the minimum value. At the same time, it also endows the module power supply with the packaging of its watch.
Aukšta kokybė patikimumas patikimumas modulis galia šaltiniai paprastai visiškai automatizuoti ir įrengti aukštųjų technologijų gamyba technologija % 2c rezultatas stabilus stabilus patikima kokybė.
Plačiai naudota: Modulinė galia šaltiniai gali būti plačiai naudojama in įvairiuose laukuose of social production and life, such as aviacija and aviacija, lokomotyvai ir laivai, kariniai ginklai, galia generacija ir paskirstymas, paštas ir telekomunikacijos ryšys, metalurgija ir kasyba, automatinė kontrolė, buitiniai prietaisai, instrumentai ir metrai, ir moksliniai tyrimai eksperimentai, specialiai in labai patikima ir aukštųjų technologijų laukai, grojimas an nepakeičiamas svarbus vaidmuo.
