N2 - This paper presents analytic solutions for the calculation of an optimal modulation scheme including frequency variation for a bidirectional single phase dual active bridge (DAB) dc-dc converter used for charging high-voltage batteries of electric vehicles. The proposed modulation scheme facilitates the minimum conduction loss operation of the DAB converter. The losses can be reduced significantly, especially for light- and medium-load conditions. Analytic expressions are derived for a direct calculation of the optimal control parameters. These expressions are verified with a numerical simulation. Moreover, a significant reduction of the necessary computational time can be achieved for the analytic determination.
