––The objective of this paper is to propose anovel multi-input power converter for the gridconnected hybrid renewable energy system in order to simplify the power system and reduce the cost. The proposed multiinput power converter consists of a Cuk fused multi-input dc–dc converter and a fullbridge dc– ac inverter. The incremental conductance method is mainly used to accomplish the maximum powe...

With the increase in applications of heavy ions in various fields, the production of intense beams of highly charged heavy ions from ion sources become more and more important. For example, the ion sources are required to produce intense dc beams of highly charged heavy ions for accelerator facilities for radioisotope beam production, and intense short-pulsed beams for injection into synchrotro...

This paper deals single phase 27-level multilevel inverter topology for DER’s-based DC/AC conversion system. This work mainly focuses on cascaded MLI using three unequal dc sources in order to produce twenty seven-level output. In this study, a high step-up converter is introduced as a front-end stage to improve the conversion efficiency of conventional boost converters and to stabilize the out...

Multiport DC–DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC–DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the pe...

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...

Introduction The widespread use of battery operated portable devices such as cell phones and laptops has created the need for DC to DC conversion power supplies such as switched mode power supplies. According to an Electric Power Research Institute (EPRI) study [1], the amount of electricity that flowed through switched mode power supplies in 2004 was “6% of the national electric bill”. The pro...

This paper deals a detailed performance investigation of asymmetrical six-phase grid connected induction generator (GCIG) in two proposed configurations variable speed operation. During the system development, regulation DC-link voltage has been using particle swarm optimization (PSO) based PI controller, ensuring power flow to utility through back converters. The closed loop operation GCIG ind...
