Abstract
In this paper, the basic principle and control strategy of a 110V/3kW two-stage dual-active-bridge-based battery energy storage power conversion system are introduced. The parameter design of its control loop is provided in detail. Meanwhile, a small-signal impedance model of power conversion system is established to analyze the stability under the condition of weak grid. In the end, the simulation and experimental results are given to confirm the feasibility of designed control loop and the correctness of proposed impedance model.
