摘要：

In this paper, a double-input bidirectional DC-DC converter is taken into account. The converter allows to use less switches than a traditional solution and, moreover, it guarantees a higher efficiency. The modulation strategy proposed in the technical literature allows the converter to work in Discontinuous Conduction Mode at low-load and, therefore, to increase the efficiency in comparison to the CCM. However, such a control reduces the dynamics of the converter. To improve the transient response, a Feed-Forward approach is proposed in this paper. Since the converter model in DCM is complex and highly nonlinear, a simplified model is considered. The effectiveness of the proposed approach is proved with experimental results on a converter prototype.
