Reduction of Reflected Power Loss in an AC-DC Converter for Wireless Power Transfer Systems

AC/DC/AC converter in a small hydroelectric power plant

The article discusses application of AC/DC/AC converter cooperating with an induction generator in small hydroelectric power plants. The induction generator works with power grid or a separated group of receivers, enabling to generate power even at low speeds of the turbine. The article provides also results of the investigation concerning the functioning of the generator coupled with AC/DC/AC ...

An Efficient Class-d Dc-dc Converter for Wireless Power Transfer Technology

The research progress in the field of Wireless Power Transmission (WPT) using Magnetic Resonance coupling with DC-DC converter. The transfer of energy from a source to a receiver has traditionally necessitated the use of a physical connection, but wireless power transfer (WPT) is essentially the transmission of an electrical current from a power source to a receiving device without the need for...

Modified Bi-directional AC/DC Power Converter with Power Factor Correction

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

Integrated control of AC-DC converter with harmonics reduction and reactive power compensation for grid application

Ac to DC converter is used for operating DC electrical machine and also supplies DC power to battery which is used for many purposes. The main purpose of this project is to compensate the harmonics by using harmonic current compensation and reactive power control. If reactive power is compensate prior to system then non linearity or harmonics present in the system does not much affect the exist...
