Modeling of a DAB under phase-shift modulation for design and DM input current filter optimization

Résumé

This paper investigates the conducted Differential Mode Current (DMC) harmonic magnitudes and the Power Factor (PF) produced by a Dual Active Bridge (DAB) converter operated under single phaseshift modulation. Power factor and the first harmonic are modeled and analyzed though a dimensionless plane of static gain versus output parametrized current. It is shown that voltage and output current ranges have a significant impact on the magnitude of the reactive power and DMC filter needs, which can therefore compromise the performance of the DAB. Especially, the DMC should be considered in the DAB converter design optimization to avoid EMI filter oversizing or non-compliance with respect to EMC standards.
