Abstract

This paper presents a generic model for the dual active bridge DC/DC converter. The model is based on the Fourier series of the switching functions of the converter. The switching functions are firstly derived with all the possible
control variables identified for the converter. The triple phase shift modulation control method is realised for this work. Other modulation methods such as the phase shift control, dual phase shift control and pulse-width modulation control can be derived from the triple phase shift control model. The dynamic
harmonic model of the DC capacitor voltages, DC currents, AC voltages and the AC inductor current are derived. The harmonic model is verified using MATLAB/Simulink software to match the derived model with a detailed switched model of the dual active bridge DC/DC converter. Further, a 500 W 24/100 V prototype is built to confirm the work.
