Abstract
A power factor controller is disclosed, in which error feedback is provided my means of a parallel combination of at least two error feedback channels. By providing at least two error feedback channels, the stability associated with, for instance, a continuously integrated feedback loop with relatively long time constant, may be combined with a fast transient response associated with, for instance, a sample-and-hold error feedback. A method of operating such a power factor controller is also disclosed.
