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...
متن کاملSeries-Resonant Single-phase AC-DC Power Supply with Control of Reactive Power
The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in dc-dc conversion. This technology transfers bulk energy efficiently through a series-resonant circuit in the direct path of the energy transfer. This resonant converter forms a high-frequency ac link between the voltage sources connected to the input and output terminals. The...

15 صفحه اولReactive Power Sharing and Harmonic Voltage Modification in Single Phase Island Micro-Grid with Drop Control
Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of...
متن کاملAn Improved Transformerless Grid-Connected PV System With Related Control Strategy to Reduce Leakage Current, Extract Maximum Power Point and Control Power
The main purposes of a transformerless grid-connected photovoltaic (PV) system consist of the reduction of leakage current, extraction of maximum power point (MPP), tracking of MPP (MPPT), controlling the active and reactive powers, and having the unity power factor. To achieve the above-mentioned aims, the following actions have been performed in this paper. First of all, a brief analysis of t...
