N2 - Dual-Active-Bridge is good candidate in electric vehicle charger, owing to bidirectional power flow and excellent galvanic. To optimize efficiency of DAB converter, many modulation strategies are proposed, including single-phase-shift, dual-phase-shift, and triple-phase-shift. The different modulation strategies can focus on realization of Zero-Voltage-Switching, minimization of reactive power and suppression of current stress, which are all improvement of steady sate performance. When utilizing multiphase-shift modulation, the dynamic response is also important in real application. In this paper, the averaged small signal models of different modulations are proposed. The different magnitude and phase performance are also discussed. An example of PI controller is proposed when using multi-phase-shift. To verify the proposed calculation and design, a Simulink model is developed, which also consider the influence of digital control in MCU.
