Abstract
A randomly snitched DC-DC converter reduces the magnitude of discrete harmonics but creates continuous noise in the output voltage. Continuo us noise within the passband of the output filter is found to induce l ow-frequency voltage ripple in the converter output. This adverse effe ct is inherent in all randomised switching schemes and is confirmed by both theory and experiment.
