In this paper, new current management ratios (CMRs) useful for managing the conduction loss, current stress, and inductor or transformer saturation are developed for a triangular modulated dual active bridge (TriMDAB) converter. The CMRs include Peak-to-DC current (P2D), RMS-to-DC current (R2D), and Peak-to-RMS current (P2R) ratios. The P2D, R2D, and P2R are respectively useful for the minimisation of the peak current, RMS current, or both. The lower the ratios, the better the performance of the converter. Firstly, the inductor peak, inductor RMS and the output (DC link) currents formulae are derived analytically. These are used to obtain the formulae for the ratios and provided useful insight about the relationship among the converter variables. The formulae developed for the ratios are simpler to use by design engineers than the inductor peak and RMS current formulae. The theory was verified by comparing the calculated ratios with the PLECS ® simulated values. The respective ratios for both cases perfectly matched. Besides the use of efficiency, the ratios further provided an alternative standard way of measuring the performance of DAB converters at different powers which engineers usually struggle with. The TriMDAB converter is usually operated in two cases: (1.) when input voltage is greater than the referred output voltage, or (2.) when the former is less than the latter. Our investigation recommends operation in the first case since there are reduced CMRs in the region.
