摘要： According to one configuration, an inductor device comprises: core material and one or more electrically conductive paths. The core material is magnetically permeable and surrounds (envelops) the one or more electrically conductive paths. Each of the electrically conductive paths extends through the core material of the inductor device from a first end of the inductor device to a second end of the inductor device. The magnetically permeable core material is operative to confine (guide, carry, convey, localize, etc.) respective magnetic flux generated from current flowing through a respective electrically conductive path. The core material stores the magnetic flux energy (i.e., first magnetic flux) generated from the current flowing through the first electrically conductive path. One configuration herein includes a power converter assembly comprising a stack of components including the inductor device as previously described as well as a first power interface, a second power interface, and one or more switches.

摘要： An apparatus such as a power supply or other suitable entity includes a controller. The controller receives a target ripple current value indicative of a ripple current associated with an output voltage and corresponding output current of a power converter powering a load. The controller selects a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value. The controller applies the selected switching frequency to switches in the power converter to produce the output current with a magnitude of the ripple current as indicated by the target ripple current value.

摘要： This disclosure includes novel ways of implementing a power supply that powers a load. A main battery source produces a main battery voltage; each of multiple auxiliary battery sources in a set produces a respective auxiliary battery voltage. A controller initially sets a battery supply voltage to the main battery voltage, the main battery voltage is supplied to a power converter. The controller then monitors a magnitude of the battery supply voltage and adjusts the battery supply voltage supplied to the power converter based on a comparison of the magnitude of the battery supply voltage with respect to a threshold level. The adjusted battery supply voltage is provided from a serial connection of the main battery source and a first auxiliary battery source in the set.
