Abstract: A system may include a power converter having a maximum allowable input power drawn from a power source, an energy storage element coupled to an output of the power converter at a top plate of the energy storage element, wherein the energy storage element is configured to store excess energy, and control circuitry configured to, when an input power of the power converter exceeds the maximum allowable input power, cause excess energy stored in the energy storage element to be consumed by circuitry coupled to the output of the power converter, and in order to maintain positive voltage headroom for the circuitry coupled to the output of the power converter, selectively couple a bottom plate of the energy storage element to the power source such that excess energy stored by the circuitry coupled to the output of the power converter is consumed from the energy storage device when the input power of the power converter exceeds the maximum allowable input power.

Abstract: A method of management of a battery that powers a component of a device may include monitoring a terminal voltage and a terminal current of the battery under a load that is drawing a current on the battery to provide power to a component of the device and modeling the battery as a battery model that approximates a relationship between the monitored terminal voltage and terminal current over at least one of: a certain frequency range; a certain duration, a certain amplitude range, an applied load, a set of conditions of the battery, and a set of conditions of the load. The relationship between the terminal voltage and the terminal current may have a frequency-dependent characteristic including at least two time constants. The two time constants may represent a time-varying relationship between an input and output of the battery model.

Abstract: A system for controlling a current in a power converter configured to generate an output voltage may include a control loop having a plurality of comparators, each comparator having a respective reference voltage to which the output voltage is compared, a digital controller configured to calculate one or more pre-seeded control parameters for the current, and an analog state machine configured to, based on outputs of the plurality of comparators, select control parameters for controlling the current. The control parameters may be selected from the pre-seeded control parameters, control parameters for controlling the current to have a magnitude of zero, and control parameters for controlling the current to have a maximum magnitude.
