This paper proposes a fast load transient control for bidirectional dual-active-bridge (DAB) DC/DC converter. It is capable of maintaining voltage–time balance during step change process so that no overshoot current and DC offset exist. The has been applied all possible transition cases the calculation intermediate switching angles referring to fixed reference points independent from converter parameters instantaneous current. results have validated by extended experimental tests.
