Apparatus, system, and method for controlling power within a power-redundant system

摘要

An apparatus may include a bus that electrically couples an electrical load to redundant power feeds. The apparatus may also include at least one capacitive component electrically coupled between first and second rails of the bus via both a conductive path and a resistive path that has substantially greater resistance than the conductive path. In addition, the apparatus may include a switching mechanism electrically coupled between the first and second rails of the bus that causes the capacitive component to charge through the conductive path until a threshold voltage on the first rail of the bus is reached. When the threshold voltage on the first rail of the bus is reached, the switching mechanism may close the conductive path and force the capacitive component to charge through the resistive path. Various other systems and methods are also disclosed.
