Accuracy Analysis of Dual Active Bridge Simulations under Different Integration Methods

One of the biggest challenge in the power electronics field is the simulation of power converters. Computer simulations and real-time simulations are really important in this field because they allow to save money during the prototyping stage and to make the entire process more efficient by predicting possible malfunctions already in the design stage. This paper introduces the impact of using different integration methods for solving the differential equations of power converters on the accuracy of the simulation. In particular, the paper focus on one of the most adopted DC-DC converter topology for automotive and microgrid applications, which is the Dual Active Bridge.
