    Recent literature consists of various optimal triple-phase-shift (TPS) modulation techniques for dual-active- bridge (DAB) converter, but there is a research gap in terms of optimal closed-form solution implementation for mission-profile specific operation. A payload mission-profile (MPL) specific optimal closed-form solution for DAB converter operation at minimum conduction loss is proposed in this paper. The conduction loss optimization algorithm, closed-form modulation solution derivation and MP L specific inductor optimization are elaborately presented. An experimental validation is performed on a 600 W, 500 kHz DAB module for a satellite payload with a defined MPL.
