摘要： A first partial power converter implementation receives and converts an input voltage into multiple auxiliary voltages including a first auxiliary voltage and a second auxiliary voltage. The first partial power converter produces a first output voltage as a first summation of the first auxiliary voltage and the input voltage; the first partial power converter produces a second output voltage as a second summation of the second auxiliary voltage and the input voltage. A second partial power converter implementation as discussed herein receives a first auxiliary input voltage referenced with respect to an output voltage of the power converter. The second partial power converter also receives a second auxiliary input voltage referenced with respect to the output voltage. The second partial power converter converts the first auxiliary input voltage and the second auxiliary input voltage into the output voltage to power a load.

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： This disclosure includes novel ways of implementing a power supply that powers a load. More specifically, a power supply includes a controller. The controller controls operation of a first power converter stage and a second power converter stage to convert an input voltage into an output voltage. For example, the first power converter stage is operative to receive an input voltage and convert the input voltage into an intermediate voltage. The second power converter stage such as a transformer-less switched-capacitor converter is coupled to the first power converter stage. The second power converter stage receives the intermediate voltage and converts the intermediate voltage into an output voltage to power a load.

The method includes selecting from operating a power converter arrangement in a single-phase mode or a three-phase mode. The power converter arrangement includes a power converter (11) having three input nodes (a, b, c) each configured to receive a respective input voltage (Va, Vb, Vc), and an output (x, z), and a buffer circuit (12) connected to the output (x, z) of the power converter (11). Operating the power converter arrangement in the single phase mode includes receiving the same input voltage (Vabc) at each of the three input nodes (a, b, c) of the power converter (11), and operating the buffer circuit to regulate at least one output voltage of the buffer circuit (12) Operating the power converter arrangement in the three-phase mode includes operating the buffer circuit (12) to regulate at least one output voltage (Vxz; Vx, Vz) at the output (x, z) of the power converter (11) such that the power converter (11) is enabled to operate in a reduced switching mode, and operating the power converter (11) in the reduced switching mode.

摘要： A power supply includes a first (main) power converter and a second (auxiliary) power converter disposed in parallel with the first power converter to produce an output voltage to power a dynamic load. The second power converter includes a primary inductive path magnetically coupled to a secondary inductive path. A controller controls a flow of first current through the primary inductive path of the second power converter to control flow of second current supplied by the secondary inductive path to the dynamic load. During steady state conditions, the first power converter produces the output voltage while the second power converter is deactivated. During transient load conditions, the second power converter provides current boost capability to maintain a magnitude of the output voltage within a desired range.
