Abstract
A circuitry for providing a power factor correction is suggested. The circuitry includes a digital pulse width modulator, a switching element, a control unit, and a combiner. An output of the digital pulse width modulator is connected to the switching element. The combiner determines a combined signal based on an output of the control unit and an input signal. The combined signal is conveyed towards the digital pulse width modulator. An output of the switching element provides a feedback signal for the digital pulse width modulator and for the control unit such that an error in the feedback signal is reduced.
