摘要： A device for power conversion includes an inductor, a switch having a switching cycle to control current flow through the inductor, a sensor coupled to the inductor to generate a signal representative of the current flow through the inductor, and a controller configured to generate a switch control signal for the switch to implement cycle-by-cycle control of the switching cycle for current-mode control of an output driven by the current flow through the inductor, the controller being coupled to the sensor such that the cycle-by-cycle control is based on the signal representative of the current flow through the inductor. The inductor is configured to exhibit a decrease in inductance with an increase in the current flow through the inductor.

摘要： A power conversion device may perform model-referenced power processing for multiple heterogenous power nodes. The power conversion device includes interconnects that couple power nodes to power converters. The power converters may include a sparse set in which the number of power converters is dependent on the model of the power source heterogeneity. The sparse set performs power processing on the power from the power node to facilitate provision of a target power at a port of the power conversion device.

摘要： A power converter device includes power converter circuitry that includes multiple inductors. The power converter circuitry may convert an input voltage and current to an output voltage and current at a variable frequency via operation of the multiple inductors. The power converter device further includes control circuitry configured to implement cycle-by-cycle current output analysis to synchronize the multiple inductors to a particular current output characteristic of a first one of the multiple inductors.

摘要： A power conversion device may perform model-referenced power processing for multiple diverse power nodes. The power conversion device includes interconnects that couple power nodes connection ports to power converters The power converters include a dense tier of power converters sized to correct from varied power flow levels of a defined portion of a population of power nodes to interim power flows in accord with center values for that portion of power nodes. The center values are provided by a model of the power node diversity. The power converters also include a sparse tier. The sparse tier performs power processing to convert from the interim power flows generated by the dense tier to a uniform model-corrected target flow.

摘要： A power conversion device may perform power processing for multiple power nodes coupled in parallel. The power conversion device includes interconnects that couple power nodes to power converters. The power converters include a dense tier of power converters sized to correct, using multiple corrective components, from varied power flow levels to interim power flows for parallel coupling of the multiple power nodes. The power converters also include a sparse tier. The sparse tier performs power processing to convert from the interim power flows generated by the dense tier to a uniform target flow.

摘要： A system includes control circuitry configured to control an output signal. The control circuitry and/or various other sources of undesirable signal components may corrupt the control signal used by the control circuitry to correct the output signal. Conditioning circuitry may effect current-domain repair on the control circuitry by providing feedback-based conditioning actuation, including comparator overdrive, to the control circuitry.
