In this paper, an integral terminal sliding mode controller (ITSMC) based on a modified exponential reaching law (MERL) is developed for providing large-signal DC-bus voltage stability while smoothing power flow in DC microgrids (DCMGs). It worth mentioning that control approach not employed DCMG applications yet to adjust the preserving balance. The proposed made up of solar photovoltaic (PV) ...

The intelligent energy management system is operated automatically to ON and OFF the generating sources as per the load demand. The renewable energy sources used in this energy management system are solar, wind, fuel cell and energy storage element battery as an input source. These renewable energy sources are integrated into the main dc bus through dc-ac converter. Microgrid is basically a gro...

-This paper proposes a new strategy for power quality (PQ) improvement in a 3-Φ grid connected Wind/PV system is proposed in this paper. The Particle Swarm Optimization (PSO) maximum power point tracking (MPPT) scheme has been used to force the PV generation to reach the maximum power operation. A battery energy storage system (BESS) along with a bi-directional DC/DC converter is introduced to ...

A novel configurable DC/DC converter architecture, to be integrated as hard macrocell in automotive embedded systems, is proposed in the paper. It aims at realizing an intelligent voltage regulator. With respect to the state of the art, the challenge is the integration into an automotive-qualified chip of several advanced features like dithering of switching frequency, nested control loops with...

Advancements in power electronics has sparked the adaptability of dc systems in varied application fields. The phenomenon of electric arcing in such dc systems, arising due to the absence of zero crossing of current during normal operation, has impeded the widespread proliferation of dc-based technologies in the market. Considering the advantages presented by adopting dc over the ac systems in ...

This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—In this paper, SHM (Selective Harmonic Mitigation) and SHE (Selective Harmonic Elimination) modulation techniques have been combined to produce appropriate pulses for four-leg three-level NPC (Neutral Point Clamped) inverter. In...

This paper deals with a control strategy used for designing energy management systems within average-power electric vehicles. The power supply system is composed of three sources, namely a fuel cell, a battery and an ultracapacitor – specialized within distinct frequency ranges – which must be coordinated in order to satisfy power demand of the vehicle’s electrical motor. The three sources with...
