Abstract
A system for controlling a current in a power converter may include an outer control loop configured to use an outer set of output voltage thresholds for an output voltage generated by the power converter in order to provide hysteretic control of the current, an inner control loop configured to use an inner set of output voltage thresholds for the output voltage in order to provide continuous control of the current, the inner control loop further configured to measure a time duration required for the output voltage to cross a single pair of two output voltage thresholds of the inner set of output voltage thresholds in order to determine an input-referred estimate of a current load of the power converter and set a peak current threshold and a valley current threshold for the current based on the input-referred estimate of the current load.
