High- Efficiency Transformer less Interleaved Boost DC-DC Converter for High-Power PEM Fuel Cell Application

摘要

In this research work a novel transformer less interleaved boost dc-dc converter for a fuel cell application is proposed. In this paper a fuel cell with a electric application, of a high power boost dc-dc converter is adopted to adjust the output voltage, current and power of fuel cell to meet requirements. The challenge in designing a boost converter for high power application is how to handle the high current at the input side and it has high switching loss. In this work an interleaved boost dc-dc converter is proposed with the absence of transformer. This converter reduces the fuel ripple current. Since the fuel cells are costly, an equivalent electrical circuit is implemented instead of a fuel cell.
