| Abstract: | When a doubly active bridge series resonant converter (DBSRC) performs phase shift switching under constant switching frequency and resonant frequency modes, significant transient oscillations occur in the resonant circuit due to the inability of its steady-state resonant voltage and current to achieve rapid transition. These transient oscillations impose substantial current and voltage stresses on power electronic devices, severely degrading the converter's output voltage quality and dynamic response performance. To address this issue, this paper proposes a novel trajectory tracking modulation method. By precisely controlling the gate signals of both primary and secondary sides of the converter, this method enables the resonant voltage and the resonant current to track the target trajectory, thereby reducing transient oscillations that may last dozens of switching cycles to within half a cycle.
