MAQOLA ANNOTATSIYASI

Maqolada optotiristorli rezistiv zanjirlar tahlili natijasi asosida optik-elektronli kontaktsiz kuchlanish relesining yangi sxemasi ishlab chiqilib, uni elektr ta'minoti tizimida ishlatish masalasi ko'rilgan hamda optotiristorlar yordamida elektr signallarni kuchaytirish yo'li bilan har hil qurilmalarning ish rejimlarini boshqarish mumkinligi va ularni elektr zanjiriga ulash to'g’risida to'xtalib o'tilgan. Optik-elektronli kontaktsiz kuchlanish relesini tajribada sinash natijasidan, kuchlanishning “kirish-chiqish” xarakteristikasi va sig’imdagi kuchlanishni egri chiziq shakli keltirilgan. Taklif etilgan sxemani takomillashtirish asosida optik-elektronli kontaktsiz kuchlanish relesining sxemasi ishlab chiqilgan va u yuqori darajadagi ishonchli-likni ta'minlaydi. Taklif qilinayotgan kuchlanish relesining sxemasi MATLAB R2014a dasturi yordamida modellashtirildi, natijada chiqish kuchlanishi egri chiziq shaklining o'zgarishini sinusoidaga yaqinligi va analitik yo'l bilan olingan natijalarga mos kelishi aniqlandi. Shuningdek, relening ishlash shartiga ko'ra yuklama kuchlanishi shaklining sinusoidaligi va qaytish koefficientining birga yaqin bo'lishiga imkon berdi.
