Abstract :
An analog-amplitude, discrete-time recursive filter is proposed for the frequency compensation of power processors. It was applied to a Cuk converter and allowed an almost ideal profile of Gloop to be reached. The filter copes with converters that chop up to 0.5 MHz and seems to be better than time-invariant compensation networks and digital-signal-processing-based filters. An exact small-signal analysis of the switching cell and the compensation filter is carried out, and experimental results on gain and phase frequency dependence are reported
