Abstract Through the analysis of the operation characteristics and problems of dual-active- bridge (DAB) DC-DC converters in the power electronic transformer (PET), this paper proposed a multi-module optimized power balance control scheme with triple phase-shift (TPS) to improve the efficiency, enhance the dynamic response and balance the transmission for the input-series-output- parallel operated DAB converters. Compared to traditional input voltage balance control scheme, the proposed control scheme can further improve the efficiency and dynamic performance under the input voltage step-change condition without increasing additional sensors. Finally, the traditional input voltage balance control and proposed multi-module optimized power balance control schemes were compared in a scale-down three-cell experimental platform using TMS320F28335+FPGA_6SLX45 as the core controller. The experimental results have verified the excellent performance of the proposed scheme and the theory analysis.

Key words： Power electronic transformer (PET) dual-active-bridge (DAB) DC-DC converter power balance efficiency dynamic performance
