Abstract :
An analog-amplitude discrete-time recursive filter is proposed for the frequency compensation of power processors. It has been applied to a converter of the type described by S. Cuk (1986), and it was allowed to reach an almost ideal profile of Gloop. 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
