Abstract
In this paper, a control strategy for an isolated DCDC dual active bridge converter to adapt different voltage levels in a DC microgrid is proposed. The control strategy allows regulating the output voltage while maintaining in zero the mean value of the current in the high frequency transformer. The system is represented with a linearized version of its generalized average model and the controller is designed using classical techniques. The performance of the proposal is validated with simulations and experimental results.
