Abstract: Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.

Abstract translation: 电力传输系统包括直流电源和可在多种模式下操作的多个输出。 接地模式可以将输出耦合到电路接地，并且电流模式可以将输出耦合到直流电源。 功率传输系统还可以包括被配置为从多个输出中迭代地选择一对输出的控制器。 一旦选择了一对，则控制器可以将一对输出的第一输出设置为当前模式和第二对地模式一段确定的持续时间。 在持续时间过后，控制器可以将第一个输出设置为接地模式，并将第二个输出设置为相同持续时间的当前模式。 此后，控制器可以选择另一对输出。
