Abstract
Methods and apparatus are provided for controlling a boost converter. In one embodiment, the method processes a command signal in a slew rate limiting circuit. The output of the slew rate limiting circuit is then processed using one or more feedback parameters from the proportional integrator to provide a processed command signal. The processed command signal is processed with a controlled signal to provide an error signal which is provided to the proportional integrator to provide a current command signal. In one embodiment, the apparatus includes an error generating circuit configured to provide a processed command signal using one or more feedback parameters from the proportional integrator, and to provide the error signal by subtracting a signal to be controlled from the processed command signal. A slew rate limiting circuit is used to receive a command signal and provide an output to the error generating circuit.
