1. A controller for a power converter, the controller comprising:
a resistor selector configured to receive a sampled voltage and generate one or more control signals based at least in part on one or more fluctuations associated with the sampled voltage; and
a variable resistor network configured to receive the one or more control signals, determine a network resistance based at least in part on the one or more control signals, and output a compensation voltage based at least in part on the network resistance.
