Abstract

Embodiments of the invention relate generally to power management and the like, and more particularly, to an apparatus, a system, a method, and a computer-readable medium for providing power controlling functionality to generate configurable power signals and to deliver power during fault conditions. In at least some embodiments, a power control unit can generate power signals having configurable attributes as a function of a mode of operation, a fault type, and the like.

Claims

a first terminal configured as a power input terminal to receive power at an input DC magnitude;

a plurality of field effect transistors (“

FETs”

) configured to receive the power at the input DC magnitude and to operate the power control unit as a buck-boost power control unit;

a first portion of memory configured to store data representing operational profiles for generating a power signal as a function of a parameter;

a mode controller configured to select an operational profile from the operational profiles to establish a selected operational profile;

a waveform control module configured to generate the power signal at an output DC magnitude in accordance with the selected operational profile;

a second terminal configured as a power output terminal to transmit the power signal at the output DC magnitude;

a second portion of memory configured to store data representing fault profiles that include thresholds for determining types of faults; and

a fault detector configured to;

detect a fault based on the fault profiles, and to

determine whether the fault is associated with a subset of faults, and to

perform a fault action.

5. The power control unit of claim 1 wherein the subset of faults comprises a first subset of faults including magnitude-based faults and a second subset of faults including time-based faults.

6. The power control unit of claim 1

wherein the waveform control module is further configured to generate another power signal as the fault action.

7. The system of power control units of claim 1, wherein the one or more waveform control modules are further configured to:

modify amounts of the power to provide portions of the power in association with the power signals at the one or more output DC magnitudes.
