Controlled concurrent utilization of multiple power supplies

Technology for concurrently powering equipment from multiple power sources, and the control thereof is disclosed. One example implementation of the technology includes a first power supply that powers equipment from a first power source and a second power supply that also powers the equipment from a second power source while the equipment is being powered by the first power supply. A target direct current (DC) output voltage of at least one of the power supplies is changed, thereby changing a ratio of the power being drawn from the first power supply to the power being drawn from the second power supply. 公开了用于从多个功率源并发地给装备供电及其控制的技术。本发明的技术的个示例实现包括从第功率源给装备供电的第电源和在该装备正由第电源供电的同时也从第二功率源给该装备供电的第二电源。至少个电源的目标直流(DC)输出电压被改变，由此改变从第电源汲取的功率与从第二电源汲取的功率的比值。
