| Summary: | Isolated bidirectional DC/DC converter is the core of power electronic transformer and influences the performance and efficiency of the system. Switching losses can be reduced and bidirectional power flow can be easily achieved with the use of series resonant dual active bridge (SRDAB) DC/DC converter. Thus a precise model is required for control system and converter design. In this paper, we took all the harmonic components into consideration, and deduced a precise steady-state modeling of SRDAB. Compares to traditional first harmonic approximation (FHA) method, the new method provides more accurate zero-voltage-switching (ZVS) turn-on condition. Effectiveness of the analysis method was validated through a laboratory prototype. |
