摘要
The bi-directional DC-DC converter is a typical hybrid power energy storage system, this paper presents a hybrid control approach for the bi-directional DC-DC converter to achieve a good control performance. The operation mode of the converter is divided into Buck mode and Boost mode according to the direction of energy flow. Considering the hybrid properties of bi-directional DC-DC converter, the hybrid automatons are obtained based on hybrid automaton theory. Then the process of control algorithm design is equivalent to the guard-selection problem of hybrid automaton. Based on the circuit theory, the guard conditions are selected. The experimental results show that the proposed hybrid control algorithm has a high degree of robustness, a low amount of computations as well as a global stability.
