Uninterruptible power supply for 48v base transceiver station (bts)

Uninterruptible power supply for 48v base transceiver station (bts) / Ahmad Syahir Saharuddin
Kebolehpercayaan bekalan kuasa tidak terganggu (UPS) stesen telekomunikasi untuk mengekalkan transmisi supaya kekal tidak terganggu sangat kritikal. Kebiasaanya, bekalan kuasa dari grid kebangsaan disokong oleh penjana bahan api fosil. Walaubagaimanapun, fenomena bencana alam seperti banjir kilat, tsunami dan gempa bumi akan dan membantutkan operasi menerima den menghantar signal di menara telekomunikasi. Di kawasan luar bandar di mana akses kepada grid kebangsaan sangat terhad ditambah dengan permukaan bumi yang tidak sekata memerlukan sumber kuasa yang stabil sebagai alternatif. Masa kini, hampir semua system telekomunikasi mengunakan bahan bakar fosil sebagai bekalan kuasa sokongan. Dengan kos bahan bakar fosil yang lebih tinggi dan harga pasaran yang tidak stabil, terdapat keperluan utama untuk mengintegrasikan sumber alternatif sebagai bekalan kuasa sokongan yang mantap sementara pada masa yang sama mengurangkan kos operasi. Dalam reka bentuk ini, gabungan utama aras ulang alik (AC) bersama tenaga yang boleh diperbaharui telah dibangunkan untuk berfungsi sebagai bekalan kuasa tanpa had yang stabil dan tidak mahal dalam membangunkan tapak stesen menerima dan menghantar signal (BTS) 48V. Bekalan kuasa yang tidak terganggu (UPS) ini disasarkan untuk isyarat 2G. Tenaga yang boleh diperbaharui adalah menggunakan tenaga suria sebagai jalan alternatif untuk mengecas storan bateri. Pengubahan antara kenaikan arus terus kepada arus terus (DC-DC) boleh digunakan untuk menaikan voltan dari 12V (dari bateri) kepada 48V (sistem telekomunikasi). _______________________________________________________________________________________________________ Reliable uninterruptable power supply for telecommunication station is very critical in order to maintain an interruptible and continuous transmission. Commonly, the main power supply for the station is delivered from the national grid and backed up by the fossil fuel generator. However, catastrophic phenomena like flood, earthquake and tsunami will isolate the station from the national grid and totally shut down the transceiver operation. In rural areas where access to national grid is very limited added with uneven earth topology, alternative sources must be obtained to provide a stable power source. For now, fossil fuel generator provides the backup power supply for almost all telecommunication systems. With the higher cost of fossil fuel and unstable market price, there is major need to integrate alternative sources as stable backup power supply while at the same time reducing the operation cost. In this design, combination of AC mains and renewable energy has been developed to serve as a stable yet inexpensive uninterruptable power supply for 48V base transceiver station (BTS) targeted for 2G network signal transmission. Solar power has been chosen as an alternative renewable energy source to charge the battery bank storage. DC-DC boost converter can be able to step up the 48V transceiver system from 12V battery storage.
