AC-DC & DC-DC Converters for DC Motor Drives
This paper deals with a comprehensive survey on the topic of AC/DC & DC/DC converters for DC Motor Drives. A substantial number of different AC/DC and DC/DC topologies appropriate for DC motor drives are presented. This critical literature review brings out merits, demerits, and limitations besides giving the basic operating principles of various topologies. Keywords—controlled-rectifiers, chop...
متن کاملDC-DC Power Converters
Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...
متن کاملControl of DC-DC Converters
A constant voltage regulator, to supply constant power loads, is realized using a Switched-capacitor converter. Exhaustive studies have been carried out to find the suitability of available control schemes and finally one control scheme investigated with (i) operation of the converter at different crossover frequencies (ii) operation of the converter at different phase Margins. Various operatin...
متن کاملHysteretic Controlled Dc-dc Converters
Chauhan, Shweta. M.S.Egr, Department of Electrical Engineering, Wright State University, 2014. Hysteretic controlled DC-DC converters. Switched-mode DC-DC converters are widely used in applications requiring stepup and step-down of DC voltages or currents. These converters find their use in portable applications such as laptops and smart phones, radio-frequency power amplifiers, as light emitti...
متن کاملPiezoelectric Converters for DC/DC and AC/DC applications
This paper introduces a cutting-edge transformer technology – the piezoelectric transformer – currently considered as a potential candidate to replace magnetic transformers in resonant switching converters. Magnetic transformers are extensively used for providing step-up and step-down voltages while allowing input to output isolation in ac-dc and dc-dc converters. Even with the extensive use, t...
