Isolated full bridge boost DC-DC converter designed for bidirectional operation of fuel cells/electrolyzer cells in grid-tie applications

Abstract: Energy production from renewable energy sources is continuously varying, for this reason energy storage is becoming more and more important as the percentage of green energy increases. Newly developed fuel cells can operate in reverse mode as electrolyzer cells; therefore, they are becoming an attractive technology for energy storage grid-tie applications. In this application dc-dc converter optimization is very challenging due to the large voltage range that the converter is expected to operate. Moreover, the… Show more

“…SiC Schottky barrier diodes are anti-parallel to the 600V IGBTs, thus the losses due to reverse recovery are negligible. IGBTs conduction and switching losses are introduced in the model based on the datasheet values [12]. The IGBTs' switching losses are initially extracted from datasheets in which the losses can be scaled for variant temperatures, and switching current and voltage.…”

“…Indeed, isolated step-down DC-DC converters (e.g., half-bridge, full-bridge) are considered to be the most attractive candidates in terms of voltage conversion ratio, since a high-frequency transformer is usually used [4]. However, the reported topologies in the literature [5][6][7][8][9][10][11][12][13][14] only feature energy efficiency improvement because of the use of soft-switching techniques at the expense of the output current ripple, reliability, and power level issues for high-power multi-source systems. Hence, to intending to increase the power level of these multi-source systems, new emerging interleaved DC-DC converter topologies have much to offer.…”
