In this paper, the TPS control with certain unified boundary condition is applied to a DBSRC. The control strategy is unified for the whole variation range of load, input/output voltage and with simple calculation. By using this unified boundary control, the circulating energy is minimized significantly. A wide soft switching operation range can be achieved. The steady-state analysis of the DBSRC will be performed using fundamental harmonics approximation (FHA) approach. The design principle for unified boundary control is then discussed. A design example based on the analysis results is presented and then verified through simulation and experiment.
