Abstract

A new and simple DC bias elimination technique for a Dual-Active-Bridge DC/DC converter is proposed in this paper. The principle is to make the positive and negative volt-seconds of the magnetizing inductance balance when the phase shift changes. This can be done with minimum disruption on the overall control system by some minor modifications on the setting of the PWM modules of the digital signal processor. Thanks to the technique, the DC bias is completely eliminated. Besides, the system dynamics is much improved.
