Abstract
A method and apparatus for estimating inductor current is provided. According to some embodiments, a method comprises generating a predicted sensed current signal for sensed current in an inductor of a power converter based on a power converter operating parameter, receiving a sensed current signal generated based on current in the inductor, compensating the predicted sensed current signal based on the sensed current signal to generate a compensated sensed current signal, generating a predicted instantaneous current signal for instantaneous current in the inductor based on the power converter operating parameter, compensating the predicted instantaneous current signal based on the compensated sensed current signal to generate an estimated instantaneous current signal, and controlling the power converter based on the estimated instantaneous current signal.
