Modern Power Electronics and AC Drives

Modern Power Electronics and AC Drives


Prentice Hall PTR | 2001 | ISBN: 0130167436 | 736 pages | PDF | 25,9 MB

An advanced, authoritative, and practical guide for state-of-the-art power electronics and AC drive technology. A clear understanding of power electronics and AC drives is crucially important in a wide range of modern systems, from household appliances to automated factories—and it requires cross-disciplinary expertise that many engineers lack. Now, in Modern Power Electronics and AC Drives, one of the world's leading experts covers every aspect of the topic, including crucial innovations such as artificial intelligence, advanced estimation, and sensorless control. This book is not only important as an advanced reference but also covers the material for one senior-level and two graduate-level courses. Dr. Bimal K. Bose discusses these key points and many more.
* Modern power semiconductor devices, converter circuits, and electrical machines
* High-performance control of induction and synchronous motor drives
* Energy saving control
* Estimation, identification, and sensorless control of drives
* Artificial intelligence techniques such as expert system, fuzzy logic, and neural network applied to power electronics and drives
* Use of MATLAB-based toolboxes in simulation and design
* Today's technology challenges—and tomorrow' Today's technology innovations make it possible to deliver higher performance, lower cost power electronics and drives for a wide range of industrial, commercial, military, utility, and residential applications. Furthermore, it can help more efficient use of electricity and thus contribute to environmental protection. If you're a practicing engineer, Modern Power Electronics and AC Drives can help you achieve these results, regardless of your previous experience.

Sampah sebagai Sumber Energi Alternatif

Sampah menjadi persoalan, khususnya di kota-kota besar di seluruh Indonesia. Timbunan sampah semakin meningkat seiring dengan peningkatan jumlah penduduk serta aktivitas ekonomi dan pembangunan. Timbunan sampah tersebut memerlukan pengelolaan dan pengolahan agar tidak menjadi sumber bencana, baik penyakit, pencemaran air tanah atau air permukaan, longsor, dan kebakaran. Salah satu teknik pengolahan dalam sistem persampahan adalah lahan urug (landfill). Dari lahan urug dihasilkan berbagai macam gas antara lain karbon dioksida (CO2) dan metana (CH4), sebagai hasil proses dekomposisi bahan-bahan organik yang terkandung dalam sampah.
 

An Overview of Switching Power Supply

Penggunaan penyedia daya tersaklar untuk berbagai aplikasi semakin digemari karena dapat mencapai efisiensi tinggi (hingga 90% untuk desain yang baik). Terdapat berbagai macam rangkaian penyedia daya jenis ini, tetapi semua rangkaian regulator tersebut selalu mempunyai 4 elemen dasar : Saklar Daya, Dioda Clamp, LC Filter, Rangkaian kontrol
