This paper treats the design, control and implementation of a non-isolated low voltage DC/DC converter with a high voltage ratio coupled a fuel cell stack and a DC bus which can be used in transport applications. The proposed converter consists of two cascade stages non-isolated DC/DC converters. The first stage is an interleaved boost converter and the second is a double dual-interleaving boost converter...
In this work, a fuel cell hybrid electric source is presented. The energy management among different components is assured by applying a control algorithm based on the nonlinear flatness principle. The studied hybrid sources use fuel cells (polymer electrolyte membrane technology) and lithium-ion batteries as main and auxiliary sources. The goal is to supply domestic load (a house), maintain the DC...
This paper presents a flatness control algorithm for a DC hybrid power sources used in Electric Vehicle (EV). The studied hybrid sources is composed by both electric sources, the first one is PEM fuel cell as the main sources, and the second one is supercapacitors pack considered as the auxiliary source. The load is connected directly in the DC link. The control algorithm is based on the flatness...
Multi-source systems are the attractive solutions in transport applications like electric vehicles. These systems are often made of the assembly of clean energy sources such as fuel cells (FC), batteries (BAT), supercapacitors (SC) and photovoltaic systems. In this paper, a multi-sources system using lithium-ion batteries considered as the main source (energy source) and SCs considered as the auxiliary...
