Improved Step Load Response of a Dual-Active-Bridge DC–DC Converter

Improved Step Load Response of a Dual-Active-Bridge DC–DC Converter

This paper proposes a fast load transient control for a bidirectional dual-active-bridge (DAB) DC/DC converter. It is capable of maintaining voltage–time balance during a step load change process so that no overshoot current and DC offset current exist. The transient control has been appli...
