Abstract

UPS (Uninterruptible Power Supply) merupakan jenis catu daya yang memiliki komponen penyimpan energi seperti baterai dengan tujuan menjaga kontinuitas aliran daya ke beban. Pada umumnya aplikasi UPS digunakan pada beban kritis, yakni beban yang tidak boleh kehilangan aliran daya secara tiba-tiba seperti komputer, peralatan medis dan kontrol industri. Dari berbagai macam topologi UPS, sistem on-line UPS sering menjadi pilihan utama karena tidak ada waktu transisi yang dibutuhkan untuk berpindah dari mode operasi normal ke mode baterai. Namun jika dilihat dari segi ekonomis, sistem on-line UPS merupakan yang paling buruk diantara topologi lainnya. Sebuah on-line UPS terdiri dari konverter AC/DC (penyearah), konverter DC/DC dua arah, komponen penyimpan energi, phase locked loop (PLL) dan konverter DC/AC (inverter). Dalam tugas akhir ini hanya dibahas mengenai perancangan konverter AC/DC dan konverter DC/AC dengan topologi half-bridge converter. Topologi ini dipilih karena jumlah komponen pensaklaran yang digunakan dua kali lebih sedikit dibandingkan dengan topologi full-bridge converter. Dengan demikian, nilai ekonomis on-line UPS diharapkan lebih baik daripada sistem on-line UPS konvensional. ======================================================================================================= UPS (Uninterruptible Power Supply) is an AC power supply featured with energy storage component such as battery in order to maintain continuity of load flow. In general, UPS used for equipment in critical applications, i.e., computers, medical equipment and industrial control. Such critical applications need uninterruptible power flow during operation. In certain applications, on-line UPS systems are often irreplaceable with other topologies because there is no transition time required for changing operation mode from normal to battery mode. However, on-line UPS systems are the worst among other topologies in terms of economic. An on-line UPS consists of AC/DC converter (rectifier), bidirectional DC/DC converter, energy storage component, phase locked loop (PLL) and DC/AC converter (inverter). In this thesis only discussed about the design of the half-bridge DC/AC converter and AC/AC converter. Number of switching components used in this half-bridge topology are two times less than used in full-bridge topology. Thus, comparing with conventional on-line UPS systems, the cost of on-line UPS systems with proposed converter are expected to be reduced.
