An analog-amplitude discrete-time recursive filter is proposed for the frequency compensation of power processors. It has been applied to a Cuk converter, and it was allowed to reach an almost ideal profile of G{sub loop}. The filter copes with converters that chop up to 0.5 MHz and seems to be better than time-invariant compensation networks and DSP-based filters. Exact small-signal analysis of the switching cell and of the compensation filter is carried out, and experimental results of gain and phase frequency dependencies are reported.
