Fuel Cell (FC) is one of the promising distributed generation resources which are based on renewable energies. Clean electricity generation, high efficiency and high energy density of the fuel cells make them attractive for lots of engineers. In this paper we discuss about the operational principles of fuel cell generally. Then, a circuit model of them will be introduced. Based on the model, we designed...
In low-power electronics, achieving a high energy efficiency has great relevance. Nowadays, global asynchronous local synchronous systems enables to use a local dynamic voltage scaling architecture. This technique allows to reach a high energy efficiency. Moreover, local dynamic voltage scaling can be implemented using different approaches. One of them is the Vdd-hopping technique. In this paper,...
Fuel cell with supercapacitors is a multi-physical system which, in association with converters, becomes hybrid. To model this complex system, different proposals have been made in literature. In this paper, Component Hybrid Dynamic Nets (CHDN) are used to model this system. CHDNs are a graphic model for hybrid systems, which allow each component of the hybrid system to be represented; moreover a...
