This paper proposes a new control method of three phase active power filterfor reducing the source current harmonics for nonlinear loads. The control strategy includes the dq transformations and hysteresis technique for current injection. Renewable energy source (solar energy) is used as a backup device for converter. Dc voltage deviations due to harmonic injections are tracked by using proport...

Energy is essential component for improving the living condition of the civilization. One of the major concerns in the power sector is that day to day increasing power demand has forced to use the fossil fuels in extreme causing the increasing serious environmental problems thus it is essential to use renewable energies which are characterized by their negligible pollution level and environment...

Maximum power point tracking (MPPT) of a photo voltaic system with different temperature and insolation conditions used for Micro grids can be explained in this paper. The micro grid conception permits small distributed energy resources (DERs) to act during a coordinated manner to produce a necessary quantity of active power and supportive service once needed. This paper proposes an approach of...

The most important component affecting the efficiency of photovoltaic power systems are solar panels. In other words, efficiency of these systems are significantly affected due to the being low efficiency of solar panel. Thus, solar panels should be operated under maximum power point conditions through a power converter. In this study, design of boost converter has been carried out with maximum...

Multi-port DC-DC converter has attracted special interest in applications where multiple energy sources are used. In this project, a three-port converter with three active full bridges, two LCC resonant tanks, and a three-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load, and a renewable source such as...

The photovoltaic (PV) generator exhibits a nonlinear – characteristic and its maximum power (MP) point varies with solar insolation. In this paper, a feedforward MP-point tracking scheme is developed for the coupled-inductor interleaved-boost-converter-fed PV system using a fuzzy controller. The proposed converter has lower switch current stress and improved efficiency over the noncoupled conve...

This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...

The demand for electricity is rapidly growing and renewable energy sources such as solar, wind tidal can compensate the to a substantial level. Among these, solar abundant, scalable cheaper. generated be used in an efficient way if DC output directly supplied load instead of converting it AC. Every electrical system capable operating and, example, Light Emitting Diode (LED) lights have become p...

This paper presents design consideration and analysis for an interleaved boundary conduction mode power factor correction buck converter. A thorough analysis on the harmonic content of the AC line current is presented to examine the allowable voltage gain (K value) for meeting EN61000-3-2, Class D while maximizing the efficiency. Results of the harmonic analysis are used to derive the required ...
