Abstract: A power electronic device includes at least one inductor configured to couple to a first capacitor and a second capacitor. The power electronic device includes a controller configured to control a first current conducting through the inductor and a second current conducting through the inductor. The first and second currents conduct in opposite directions with respect to each other, and the first and second currents interact with each other through the inductor such that a net direct current (DC) component through the inductor is approximately zero.

Abstract: A trolley interfacing device for interfacing a traction load to a voltage source is presented. The trolley interfacing device includes a first charging unit coupled in parallel to the voltage source. Further, the trolley interfacing device includes a second charging unit coupled in parallel to the traction load, where the second charging unit includes at least one inductor. Also, the trolley interfacing device includes a pre-charging unit coupled in parallel to the second charging unit and configured to pre-charge the first charging unit with a voltage across the at least one inductor prior to electrically coupling the first charging unit to the voltage source. In addition, the trolley interfacing device includes a voltage converting unit disposed between the first charging unit and the second charging unit and configured to step down a voltage provided by the voltage source to the traction load.
