    • Embodiments of the invention can provide systems, methods, and apparatus for cooling a power conversion system. According to one embodiment, a system comprising a power conversion system having an electrical component with a magnetic core can be provided. The system can include a heat transfer path adjacent to a portion of the electrical component and electrically isolated from the electrical component. The system can also include a cooling medium. The cooling medium can be used in conjunction with the heat transfer path for transferring heat from the electrical component. At least in this way, a system for cooling a power conversion system can be provided that can reduce thermal effects associated with power conversion.

    • A power conversion system for providing power to an electrical grid is described. The system includes a power converter coupled to a direct current (DC) power source. The system also includes a contactor coupled to the power converter and the electrical grid and configured to selectively electrically couple the power converter to the electrical grid. The system also includes a system controller communicatively coupled to the power converter and the contactor and configured to close the contactor to electrically couple the power converter to the electrical grid and to activate the power converter when a DC voltage provided has remained higher than a voltage level for a length of time. The system controller is also configured to deactivate the power converter, while the contactor is maintained in the closed position, when an alternating current (AC) power output has remained lower than a power level for a length of time.

    • An apparatus and method for improved current shunt sensing in an electrical system, such as a renewable energy electrical system, is disclosed. A current shunt according to aspects of the present disclosure includes a conductive portion that is placed in series with an electrical system The current shunt includes a sensing element that is used to measure the voltage across the conductive portion of the current shunt. The sensing element has an increased width relative to the width of the conductive portion of the shunt. The increased width of the sensing element provides for improved current shunt sensing that results in more accurate voltage (and thus current) measurements across a wide range of frequencies.
