SMPS Nedir ve EV’ler \u0130\u00e7in Neden \u00d6nemlidir?<\/h2>\n

En basit tabiriyle, Anahtarlamal\u0131 Mod G\u00fc\u00e7 Kayna\u011f\u0131, y\u00fcksek frekanslarda a\u00e7\u0131l\u0131p kapat\u0131lan anahtarlama cihazlar\u0131 (tipik olarak MOSFET’ler veya IGBT’ler) kullanarak g\u00fcc\u00fc d\u00f6n\u00fc\u015ft\u00fcren bir elektronik devredir.<\/p>\n

Fazla voltaj\u0131 \u0131s\u0131 olarak da\u011f\u0131tan geleneksel do\u011frusal g\u00fc\u00e7 kaynaklar\u0131n\u0131n aksine, bir SMPS, giri\u015f voltaj\u0131n\u0131<\/a> y\u00fcksek frekansl\u0131 darbelere “b\u00f6ler”.

Bir PandaExo \u015farj istasyonunda bir SMPS’nin nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131 anlamak i\u00e7in s\u00fcreci d\u00f6rt ana a\u015famaya ay\u0131rabiliriz:<\/p>\n

1. Giri\u015f Do\u011frultma ve Filtreleme<\/h3>\n

S\u00fcre\u00e7, \u015febekeden gelen ham AC g\u00fcc\u00fcyle ba\u015flar (tipik olarak AC \u015farj cihazlar\u0131 i\u00e7in 110V\/220V veya DC istasyonlar i\u00e7in 480V \u00fc\u00e7 faz). Bu AC voltaj\u0131, d\u00fczensiz bir DC voltaj\u0131na d\u00f6n\u00fc\u015ft\u00fcrmek i\u00e7in bir k\u00f6pr\u00fc do\u011frultucudan<\/a> ge\u00e7irilir. Daha sonra y\u00fcksek kaliteli kapasit\u00f6rler bu DC’yi filtreleyerek “dalgalanmay\u0131” giderir ve d\u00f6n\u00fc\u015f\u00fcm i\u00e7in kararl\u0131 bir ba\u015flang\u0131\u00e7 noktas\u0131 sa\u011flar.<\/p>\n

2. Y\u00fcksek Frekansl\u0131 Anahtarlama (\u0130nvert\u00f6r A\u015famas\u0131)<\/h3>\n

\u0130\u015fte sihir burada ger\u00e7ekle\u015fir. Filtrelenmi\u015f DC, y\u00fcksek h\u0131zl\u0131 bir anahtarlama eleman\u0131na beslenir. Ak\u0131m\u0131 saniyede on binlerce veya y\u00fcz binlerce kez (kHz) de\u011fi\u015ftirerek sistem, y\u00fcksek frekansl\u0131 bir AC sinyali olu\u015fturur. Bu, geleneksel g\u00fc\u00e7 sistemlerinde bulunanlardan \u00e7ok daha k\u00fc\u00e7\u00fck transformat\u00f6rlerin kullan\u0131lmas\u0131na olanak tan\u0131r.<\/p>\n

3. Voltaj D\u00f6n\u00fc\u015f\u00fcm\u00fc ve \u0130zolasyon<\/h3>\n

Y\u00fcksek frekansl\u0131 AC, y\u00fcksek frekansl\u0131 bir transformat\u00f6rden ge\u00e7irilir. Bir EV ba\u011flam\u0131nda bu iki amaca hizmet eder:<\/p>\n
