A Current Sharing Control for Input-parallel Output-parallel Dual Active Bridge Converters
In order to improve power capacity of dual active bridge converter,various modular combinations have been proposed.Based on modular combination of input parallel output parallel,this paper first establishes the reduced order small signal model of the converter,then analyzes the principle of current balance between phases of the converter,and obtains the estimation method of inherent phase parameters and parallel current sharing control strategy.Finally it verifies rationality and correctness of the proposed control method using simulation model.
