Abstract
A controller for a power converter includes a first amplification stage and a second amplification stage coupled to the first amplification stage. The first amplification stage generates a first amplified signal at a first terminal of an energy storage element according to an output signal the power converter. The second amplification stage generates a second amplified signal at a second terminal of the energy storage element and varies the second amplified signal in response to a change in the output signal. The second amplification stage further decreases the variation of the second amplified signal based on the first amplified signal.
