Description
Summary:Low - loss, high - efficiency DC - DC converters are key components for applications such as interconnection of photovoltaic (PV) systems, wind power systems, energy storage systems (ESS), electric vehicles (EV), power electronic transformer (PET), and DC microgrids. Prior to laboratory implementation, it is essential to obtain an accurate calculation of power losses in the converter. In this work, an accurate analytical calculation of losses in a Full - Bridge DC-DC Converter (FBDC) is presented and validated with simulation results. The analytical calculation presented shows the analysis both in the rectification section and in the inverter section, in addition to the Medium Frequency Transformer (MFT) analysis. The results obtained are validated by simulation (Matlab - Simulink). The obtained efficiency and losses in the FBDC converter are 96.6% and 31.56W, respectively. The results obtained provide a contribution to the designers of DC - DC converters.
