Abstract:

The growing interest towards efficient and reliable bidirectional DC-DC converter topologies for interfacing low-voltage (LV) batteries, eg. 48 V, with a high-voltage (HV) DC-link, eg. 400 V, has driven the research toward the investigation of many different topologies. In this paper, three isolated and bidirectional topologies have been selected and compared to each other, where these topologies are seen as the state-of-the-art topologies for battery-fed systems. The introduced comparison includes the number of used semiconductor devices and passive elements, the rated voltage and current of the different semiconductor devices, the forecasted switching and conduction losses using PLECS, and the estimated volume and power losses of the employed magnetic elements. Furthermore, the comparison includes simulation results using PLECS considering a 1.5 kW power level.
