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.

Abstract: A battery management system configured to electrically couple to a battery may include a boost converter comprising a plurality of switches arranged to provide a boosted output voltage at an output of the boost converter from a source voltage of the battery and a bypass switch coupled between the battery and the output, wherein the battery management system is operable in a plurality of modes comprising a bypass mode wherein the source voltage is bypassed to the output and when the battery management system is in the bypass mode, at least one switch of the plurality of switches is enabled to increase a conductance between the battery and the output.
