Switched-capacitor power electronics circuits - IEEE Circuits and Systems Magazine
One of the main orientations in power electronics in the last decade has been the development of switching-mode converters without inductors and transformers. Light weight, small size and high power density are the result of using only switches and capacitors in the power stage of these converters. Thus, they serve as ideal power supplies for mobile electronic systems (e.g. cellular phones, per...
متن کاملHigh Power Laser Diode Driver Based on Power Converter Technology - Power Electronics, IEEE Transactions on
This paper describes the design of a high speed semiconductor laser diode driver designed for driving 500 mW to 1.5 W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in previous designs, allowing for a more modest power...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولFast Controller for a Unity-Power-Factor PWM Rectifier - Power Electronics, IEEE Transactions on
This paper presents an analog implementation of a fast controller for a unity-power-factor (UPF) PWM rectifier. The best settling times of many popular controllers for this type of converter are on the order of a few line cycles, corresponding to bandwidths under 20 Hz [l]. The fast controller demonstrated in this paper can exercise control action at a rate comparable to the switching frequency...
متن کاملSimple Digital Control Improving Dynamic Performance of Power Factor Preregulators - Power Electronics, IEEE Transactions on
This paper presents the practical implementation of a fully digital control for boost power factor preregulators (PFP’s). The control algorithm, which is simple and fast, provides a significant improvement in the system’s dynamic performance compared to usual analog control techniques. The paper discusses the design criteria and the actions taken for the implementation of the digital control, w...
