Paper Abstract

A digital controller for high frequency Switching Power Supply based on Sigma Delta modulation is proposed in this work. A technique to restrict average switching frequency in a suitable range is used. The complete system has been modelled and simulated at system level using the SystemC-WMS environment. A high precision controller has been designed with relatively low clock frequency and area occupancy of the Sigma Delta modulator, and at the same time reducing the sensitivity to parameter statistical variations and to temperature drift.
