A method and circuit for controlling feedback in, for example, a power factor converter circuit. A current sense signal is compared with a reference signal to generate a comparison signal. A clipped signal is generated from the comparison signal where the signal is a periodic waveform that transitions between two levels that are symmetrically positioned about a reference signal. The clipped signal is used to generate a summed signal at the input of an integrator. The integrator generates a feedback signal suitable for use in, for example, a power factor converter circuit. |
