Abstract

In this paper, the Dual Active Bridge (DAB) converter used to interface batteries for 270/28V on-board grid in More electric aircraft (MEA) applications is investigated. In order to transfer the desired rated power of 3kW, the low voltage terminal current is controlled. For such reason, a Model predictive control (MPC) method is proposed with the aim of achieving fast dynamic performance. However, due to the unexpected DC offset under steady state operation, another MPC strategy is developed aiming to eliminate this offset and improve the system efficiency. The second MPC method is evaluated based on the comparison with the traditional Proportion Integration (PI) control method. Simulation results for a 270/28V DAB converter rated at 3kW are presented for the validation of the proposed method.
