Kurzfassung englisch:
The conventional step-down converter is powered by a voltage source. Some applications, e.g. railway power supplies, need a step-down and inductive input characteristic. The proposed structure is compared with the conventional step-down converter with LC input filter. One surprising advantage is that the current rating of the inductor L2 is half the value of the corresponding inductor in the conventional structure by identical ratings of all other devices when it is operated above 50% duty cycle. PSPICE simulation is performed to show the dynamic behavior. The structure is well suited for unidirectional DC voltage adaptation, (the voltage of the DC power grid exceeds the voltage rating of the DC-load).
