Closed-Form Second-Order Power Transmission Characteristic Model of the Isolated Dual Active Bridge Converter

Yunpeng Yao, Shen Xu, Shengli Lu, and Weifeng Sun
Abstract—The closed-form second order power transmission characteristic (SO-PTC) models of the isolated dual active bridge (IDAB) converter is proposed in all the control strategies in this paper, and the SO-PTC model is derived by the fundamental harmonic approximation (FHA) method. This SO-PTC model shows a better accuracy and a good convenience in predicting the output power of the DAB converter in practical applications. By using this model, the designer can calculate the maximum acceptable parasite resistance of the DAB converter according to the targets of the design; these targets include the efficiency, the voltage conversion ratio, the maximum output power, and so on. Based on the calculated maximum acceptable resistance, the choice of the power switches, the design of PCB and the calculation of the turns on the two sides of the transformer can be facilitated. The validity of the proposed SO-PTC model is verified on a 100W prototype.

Index Terms—Power transmission characteristic, FHA, model, efficiency, dual active bridge.
