A coordinated experimental and theory/simulation effort has been carried out to investigate the physics of the Traveling Wave Direct Energy Converter (TWDEC), a scheme that has been proposed in the past for the direct conversion into electricity of the kinetic energy of an ion beam generated from fusion reactions. This effort has been focused in particular on the TWDEC process in the high densi...
The matrix converter (MC) for motor drive applications and energy conversion systems is steadily increasing due to its main advantage of performing a direct coupling between two three-phase alternating current sources without the need of an intermediate direct current bus. The input filters characteristics design for matrix converter system: to reduce the high harmonic components at the main po...
Renewable energy generation systems, based on photovoltaic sources, currently represent the most suitable solution, for low power levels, to reduce the energy consumption produced by oil and gas. Moreover, they are becoming more and more attractive as the price per watt of the photovoltaic modules is decreasing. However, the conversion efficiency of commercial photovoltaic modules is still rath...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....
Photovoltaic (PV) cell converts sunrays into electrical energy, which has non-linear I-V characteristics. For extracting maximum power from photovoltaic (PV) array for varying environmental conditions, it is necessary to use MPPT tracker. The MPPT consists of DC-DC converter and MPPT algorithm, DC-DC converter is inserted between solar panel and load or battery. The task of MPPT tracker is to m...
Among the many advantages that resonant power conversion has over conventionally adopted pulsewidth modulation include a low electromagnetic interference, low switching losses, small volume, and light weight of components due to a high switching frequency, high efficiency, and low reverse recovery losses in diodes owing to a low di/dt at switching instant. This work presents a novel loaded-reso...
Wind is one of the most prominent renewable sources of energy. Wind energy conversion system (WECS) is based on a variable speed wind turbine with direct driven permanent magnet synchronous generator (PMSG) and transmits its electrical power to an AC grid using advanced power electronic converter system. This paper describes operation and control of variable speed WECS based on gearless PMSG to...
Interlink Converter with Linear Quadratic Regulator Based Current Control for Hybrid AC/DC Microgrid
A hybrid alternate current/direct current (AC/DC) microgrid consists of an AC subgrid and a DC subgrid, and the subgrids are connected through the interlink bidirectional AC/DC converter. In the stand-alone operation mode, it is desirable that the interlink bidirectional AC/DC converter manages proportional power sharing between the subgrids by transferring power from the under-loaded subgrid t...
