N2 - In this article, dual-active-bridge (DAB) dc-dc converter with phase shift control is explored extensively, and optimal performances obtained with different objectives are comparatively analyzed in each mode. First, the principle and operating modes of TPS control are introduced in detail. Second, the electrical characteristics of the converter in each operating mode are systematically derived. Third, resonant commutation in each dead-band is analyzed, and soft-switching areas of the converter are obtained. Then, based on zero-voltage switching (ZVS), peak, and root mean square (rms) of the inductor current, backflow power and operating losses are taken as optimization objectives, and the obtained optimized results are contrastively analyzed. The commonalities of the optimization results with different objectives in modes I-III are revealed, and the differences in optimization characteristic in mode IV are present, as a guidance for practice design and operation. Experiments are performed to demonstrate the theoretical analysis.
