N2 - To eliminate the dc-bias current in the transient-state (TS) of the dual-active-bridge (DAB) DC-DC converter with the load change demand, this paper proposed an optimized transient modulation (OTM) control strategy under triple-phase-shift (TPS) control for transient response. Compared with the traditional optimized algorithm in TS, a fixed switching state is applied to increase the transition speed and simplify the complexity of calculations. Because of the fixed switching state, the gradient of the inductor current is modified to the maximum value rather than piecewise linear relationship within the transient period, which shorten the settling time significantly. Besides, compared with the dedicated method for specific phase-shift control of traditional optimization, OTM control is not only suitable for TPS control, but can be utilized for other phase-shift control easily as well, such as extended-phase-shift (EPS) and single-phase-shift (SPS). Finally, the experimental results are given to verify the proposed OTM methods.
