Abstract :
Recently great effort has been done in the development of high efficient DC-AC switching power converters for renewable energies and in particular for solar cells. The common algorithm used to control DC-AC switching power converters is Pulse Width Modulation. The present work presents the use of Sigma-Delta modulators for the control of the switches of DC-AC switching power converters. The proposed control algorithm presents the advantage of a reduction of conducted electromagnetic interferences with respect to Pulse Width Modulation. A DC-AC switching power converter has been simulated using SystemC-WMS and a prototype has been implemented.
