    Abstract: An apparatus includes a substrate and a matrix having multiple cells embedded within the substrate. The matrix is configured to generate electrostatic fields to define at least one flow path for liquid metal. The apparatus also includes a pump configured to create movement of the liquid metal through the at least one flow path defined by the matrix. The matrix is configured to transport the liquid metal through the at least one flow path in order to remove thermal energy from one or more areas of the substrate. The matrix could include a matrix of capacitors, and polarities of charges stored on the capacitors could define which cells allow passage of the liquid metal and which cells block or restrict passage of the liquid metal. The cells that block or restrict passage of the liquid metal could be configured to increase a viscosity of the liquid metal.

    Abstract: A regulated current-fed power system employs power branching units connected in series. Each power branching unit includes a plurality of parallel-redundant converter groups connected in series with each other within a current path for the regulated current. Each parallel-redundant converter group includes at least two direct current (DC)/DC converters connected in parallel with each other, each sharing the power load. A protection device connected in series with each DC/DC converter disconnects the respective DC/DC converter from the regulated current when the respective DC/DC converter short circuits, with the remaining DC/DC converter(s) then receiving more of the power load. An active clamp connected in parallel with all of the DC/DC converters within a parallel-redundant converter group temporarily sinks a portion of the regulated current when one of the DC/DC converters fails in a short-circuit condition. The active clamp shunts the regulated current around all DC/DC converters within the parallel-redundant converter group converters fail in a short-circuit condition.

    Abstract translation: 调节电流馈电系统采用串联连接的功率分支单元。 每个功率分支单元包括在用于调节电流的电流路径内彼此串联连接的多个并联冗余转换器组。 每个并联冗余转换器组包括至少两个彼此并联连接的直流(DC)/ DC转换器,每个共享电力负载。 与每个DC / DC转换器串联连接的保护装置在相应的DC / DC转换器短路时与相应的DC / DC转换器断开,DC / DC转换器的短路随着其余的DC / DC转换器接收到更多的功率负载 。 在并联冗余转换器组中的所有DC / DC转换器并联连接的有源钳位器当其中一个DC / DC转换器在短路状态下故障时,临时吸收一部分稳压电流。 并联冗余转换器组转换器中的所有DC / DC转换器的有源钳位分流调节电流处于短路状态。
