Description
Summary:This paper presents a steady state analysis of the commutating LC-filter based dual active bridge (DAB) considering the conduction losses in the components. The aim is to use this converter in power electronic transformer (PET). The LC-filter offers the boost properties with a small component count and DAB allows effective power flow control and soft switching capabilities. Such combination allows the voltage on the transformer terminals to be kept at the desired level to enable the best performance of the converter. In order to facilitate the impact of the losses on the power characteristics and efficiency the mathematical loss models are derived and experimental results are presented.
