Efek Perubahan Frekuensi Switching Pada LED Driver Dengan Topology Boost
Abstract
Light Emitting Dioda (LED) yang serbaguna, hemat energi bila dibandingkan dengan sumber cahaya konvensional. LED driver merupakan konverter DC-DC dengan MOSFET sebagai komponen utama untuk switchingnya. Namun sebuah LED dapat menimbulkan emisi EMI yang dapat mengganggu performansi LED itu sendiri dan elektronik disekitarnya. Sumber utama emisi EMI pada LED driver berasal dari switching MOSFET yang menggunakan sinyal Pulse Width Modulation (PWM). Pada proyek akhir ini akan dilihat efek perubahan frekuensi switching yang terjadi pada LED driver dengan topology boost converter. Pada proyek akhir ini akan dilihat bagaimana efek perubahan dari frekuensi switching.References
