Abstract A unified phasor analytical method is introduced in this paper to analyze the control and power characteristics of bi-directional dual-active-bridge dc-dc converter under all phase-shift control strategies. Fourier transform theory is utilized to translate time-domain differential equation of ac-ac stage in dc-dc converter into steady-state phasor expression. Hence, the phasor diagrams are plotted. The respective control regions for single-phase-shift control, extended-phase-shift control and dual-phase-shift control are proposed. A uniform complex power model is built which holds for all phase-shift controls. The simulations and experimental results show good coherence to the theoretical analysis, and also show the applicability and creditability of the proposed model and unified phasor analytical method.
