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.

A power converter is presented. The power converter includes a primary bridge unit coupled to a voltage source. Further, the power converter includes a secondary bridge unit coupled to a load. Also, the power converter includes a transformer disposed between the primary bridge unit and the secondary bridge unit and configured to magnetically couple the primary bridge unit to the secondary bridge unit. Additionally, the power converter includes a current sensor configured to measure instantaneous current flowing at an input terminal of the transformer. Furthermore, the power converter includes a cyclic state controller configured to receive the measured instantaneous current flowing at the input terminal of the transformer, and change a switching state of the power converter from a present switching state to a subsequent switching state based on the measured instantaneous current.

A power generation system () for generating electrical power, which may vary in response to one or more weather-varying factors (). The system may include an array of power generators () subject to the weather-varying factor. A module () may be configured to predict over a time horizon at least one power-generating condition for the array of power generators. A controller () may be configured to anticipatorily adjust a control strategy regarding operation of a component and/or subsystem of the power generation system based on the predicted power-generating condition for the array of power generators over the time horizon.
