    Abstract: A system and method for conditioning DC power received from hybrid DC power sources is disclosed. A power conversion circuit is coupled to a respective DC power source to selectively condition the output power generated thereby to a DC bus voltage. The power conversion circuit includes a switch arrangement and capacitors arranged to provide a charge balancing in the power conversion circuit. A controller in operable communication with the switch arrangement receives inputs on a DC bus voltage and at least one parameter related to operation of the DC power source, and determines an adjustable voltage to be output from the conversion circuit to the DC bus based on the received inputs. The controller then selectively controls operation of the switch arrangement in order to generate the determined adjustable voltage.

    Abstract: A power conversion system is presented. The system includes a power source coupled to a power converter and a controller. The controller is configured to determine a value of at least one parameter corresponding to the power source. Additionally, the controller is configured to provide a first portion of the at least one parameter to the power converter and modify an operating frequency of the power converter, duty ratio of the power converter, or a combination thereof. Furthermore, the controller is configured to obtain an electrical quantity at an output of the power converter based on the modified operating frequency, the modified duty ratio, or a combination thereof. Also, the controller is configured to deliver a combination of the electrical quantity obtained at the output of the power converter and a second portion of the at least one parameter to a load. Method for converting power is also presented.

    Abstract: The present disclosure presents techniques to facilitate improving operation of an electrical system, which includes a bus structure that cascades multiple electrical devices. The bus structure includes a first outer conductive layer implemented as a positive layer; a second outer conductive layer implemented as a negative layer; a first intermediate conductive layer neighboring the first outer conductive layer; a second intermediate conductive layer neighboring the second outer conductive layer; and a third intermediate conductive layer neighboring the second intermediate conductive layer, in which the third intermediate conductive layer is implemented as an inter-device layer that facilitates electrically coupling at least two of the electrical devices in series. The first intermediate conductive layer is implemented as a negative layer and the second intermediate conductive layer is implemented as a positive layer to facilitate reducing stray inductance and/or increasing stray capacitance introduced in the electrical system during operation.
