Abstract
A method for regulating a buck converter, in which the amount of the output volume is adjusted via a controlled switching, comprising a pulse sequence having a pulse rate and being pulse width modulated, and an inductor, which is switched serially with a load over which an output voltage drops, and an arrangement with a control input and with a control output, between which an analog-to-digital converter, a non-linear amplifier, an IIR filter, and a pulse width modulation circuit is switched, to allow a quick reaction upon a load transient by which the regulation of the output voltage at a buck converter occurs faster and with less overshooting. This is attained such that the sample rate is adjusted to be greater than the pulse rate and the pulse values of the pulse sequence are controlled during the cycle duration.
