Abstract :
The Sigma delta modulation advantage is its special power spectrum density which is better from other modulation techniques from EMC point of view. The disadvantage of this modulation technique is its low dynamic response in the case of using conventional control methods. The proposed digital control method of this paper improves the dynamic response of boost power factor correction pre-regulator. Simulation results show the capability of the proposed modulation technique.
