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