This paper presents an energy management method in an electrical hybrid power source (EHPS) for electric vehicular applications. The method is based on the flatness control technique (FCT) and fuzzy logic control (FLC). This EHPS is composed of a fuel cell system as the main source and two energy storage sources (ESSs)—a bank of supercapacitors (SCs) and a(More)
In this paper, an analysis of two-phase interleaved boost converter working in both CCM and DCM is presented. This kind of DC-DC converters is usually used as a bridge to increase the output voltage level to a suitable one compared to the input voltage like fuel cell converter. Interleaving technique can be used to reduce current ripples of DC-DC converter(More)
In this paper, a transformer for an N-port isolated bidirectional DC-DC converter is presented. This converter can be used in hybrid renewable energy systems where many of energy sources and storage devices and load are required. The final model allows simple calculation of the exchanged power between ports. The example of three-winding transformer for a(More)
In this paper, a nonlinear control algorithm for a current-fed DC-DC is presented. This converter consists of an inductor, a controllable full-bridge converter, which is connected to a full-bridge rectifier via a high-frequency transformer. The advantages of this converter include galvanic isolation, high voltage gain and low input current ripple. Based on(More)
In this paper, implementation results of two different topologies for a fuel cell-supercapacitor (SC) hybrid system are presented. In first topology, the SC bank is connected to a low voltage DC-bus while in the second one, it is connected to a high voltage DC-bus through a DC-DC converter. The energy management is carried out in both the topologies with(More)
