Abstract

In this contribution, a control scheme for n-leg interleaved DC/DC converters is presented, allowing dead beat
current control. Accurate average current control is ensured even for nonlinear filter components such as iron powder inductors or ferrite core inductors used near their saturation limit.
Furthermore, the control scheme features a common measurement instant for all measured values. The effectiveness of the proposed control scheme is shown with a three leg bidirectional DC/DC converter.
