Interleaved double dual boost (IDDB) DC-DC converters are widely used in high-power renewable energy conversion applications, which can provide both high step-up ratio and low current ripple. This paper is focused on the nonlinear modeling and control of non-ideal IDDB converter. A sliding mode controller is design based on the model with parasitics considered. Some key issues on the control design...
This paper presents a novel non-isolated switched inductor floating output DC-DC multilevel boost converter. Non-isolated high gain DC-DC converters are essential for fuelcell applications to boost the supply voltage with high conversion ratio. Conventional DC-DC boost converter is not suitable for high gain applications because of high voltage stress and high duty cycle. The proposed converter is...
In this survey paper, applications of medium voltage direct current (MVDC) to distribution substations are discussed and compared to conventional ac for power conversion from transmission voltage levels to distribution voltage levels. Technical changes in the substation due to the dc equipment, efficiency of the substation, and protective measures are major aspects to consider in the MVDC concept...
Renewable energy sources has been attracting great interest due to well known environment issues and, hence, the development of power electronics converters to deal with the transformation of these sources into conventional energy forms has been the main challenge faced by many researches working in this area of expertise. Within this subject, this paper focuses the establishment of a simple power...
PEMFC has being applied more and more in automobile and distributed generation for its low corrosion, low-temperature operation and environment-friendship a complex systems and it is expensive. It should be concerned over the control and maintenance of its auxiliary equipments, placement site, restoring of hydrogen and the other when real PEMFC is used. However, PEMFC's volt/ampere external characteristics...
This paper focuses on the novel controller design and analysis for a fuel cell vehicle energy storage system energy management system, based on a hybrid switched-capacitor (SC) bidirectional DC/DC converter topology. The novel control strategy enables simpler dynamics compared to a standard buck converter with input filter, which is essential for fuel cell based energy storage systems. Moreover, the...
This paper presents a new climate friendly cost-effective inverter for residential fuel cell applications. Meeting this need was one of the objectives for the 2007 Future Energy Challenge, a contest sponsored by the US Department of Energy, US Department of Defense and the IEEE. The aim of this paper is to design, simulate, and build a scale model of a 5 kVA inverter capable of performing the power...
