In this letter, two different phase-shift modulation used for the transient response of a dual-active-bridge dc/dc converter and their effects on the dynamics of the converter are discussed and compared. It is found that the settling time for both cases depends on the value of the equivalent series resistance of the power inductor. To minimize the transient time, a modified asymmetric double-side modulation is proposed, which enables the converter to transfer smoothly from one steady state to another one regardless of the equivalent series resistance of the power inductor. Experimental results of the dynamics of the converter using different transient modulation techniques are also included for the purpose of validation.
