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...
Medium-voltage conversion systems, such as traction and grid-connected converters, are continuously evolving toward higher power densities. Consequently, volume, weight, and material reductions are becoming major design issues, which lead the research focus toward high-/medium-frequency isolated power conversion systems. An optimized design of these conversion systems requires a detailed transformer-loss...
This paper is going to develop two soft switching DC-DC converters based on the half-bridge inductive converter for the design of the power electronic interface for fuel cell applications. One operates in ZVS mode, another in ZCS mode. The ZVS converter can overcome the drawbacks of the original structure but is more complicated. The ZCS converter can't operate at the duty cycle less than 0.5 but...
