ЖАҢА ГИБРИДТІ ЖАРЫҚДИОДТЫ ДРАЙВЕР

Мақалада жаңа гибридті жарықдиодты драйвер (hybrid LED driver) ұсынылады. Гибридті жарық диодты драйвер желіге тікелей қосылу үшін жарықдиодты модульдегі (Direct ACLED module) кіріс кернеуімен синхронды түрде жарықдиодты жолақтарды ауыстыру идеясын және дәстүрлі жарықдиодты драйвердегі (LED driver) импульстік қуатты түрлендіру принципін біріктіреді. Мұндай біріктіру тиімділікті арттырады, электромагниттік кедергілерді азайтады. Қуат шығынының төмендігі арқасында гибридті жарықдиодты драйвер микросхемаға біріктіруге тиімді және қазіргі уақытта қолданылатын дәстүрлі жарықдиодты драйверлермен салыстырғанда өлшем мен шығындарды азайтуға мүмкіндік береді. Алдыңғы деңгейдегі гибридті жарықдиодты драйверлерде жарықдиодты шамдар коммутациялық режимде жұмыс істейді, бұл жарықдиодты шамдардың баяу жұмыс істеуіне байланысты тиімділікті шектейді. Сонымен қатар, мұндай жарықдиодтарының сәулелену қарқындылығы импульстік режимде төмендейді. Ұсынылған жаңа драйвер тиімділікті арттыратын және электромагниттік кедергілерді азайтатын жарық диодтарының қатты жұмыс режимін жоққа шығарады. Мақалада жаңа гибридті драйверге талдау жасалады. Алынған нәтижелерді растау үшін мамандандырылған бағдарламалық жасақтаманы қолдана отырып компьютерлік модельдеу жүргізілді.
