Patent ID: 8143871

Claim:
A dynamically-compensated controller for generating a switching signal for a DC power supply having as output comprising: a feedback circuit configured to: generate the switching signal based on a feedback signal that is indicative of the output of the DC power supply; adjust one or more performance characteristics of the feedback circuit based on one or more optimization signals; and perturb the switching signal based on a test perturbation signal; an optimizer circuit configured to generate the optimization signals based on information indicative of the performance characteristics of the feedback circuit; a test perturbation signal generator circuit configured to generate the test perturbation signal; and an analyzer circuit configured to generate the information indicative of the performance characteristics of the feedback circuit based on a signal representative of the output of the DC power supply and information about the test perturbation signal, the analyzer circuit including: a DC removal circuit configured to substantially remove the DC component of the signal representative of the DC output of the power supply so as to produce a filtered output signal representative of the test perturbation on the output of the DC power supply caused by the test perturbation signal without the DC component; and a frequency translation circuit configured to translate the frequency of the filtered output signal to a frequency that is lower than the frequency of the test perturbation signal.
