1. A system, comprising:
a filter circuit configured to:
receive an input voltage; and
provide an output current;
a power conversion circuit coupled to the filter circuit and configured to:
receive the output current; and
provide an output voltage; and
a power factor correction controller circuit configured to:
receive a signal representing the input voltage;
receive a signal representing the output current;
determine a tracking error associated with the power conversion circuit based on the input voltage and the output current; and
determine an adjustment to the output current based on the tracking error.
