Abstract
In this paper, a predictive non-linear voltage mode control method is introduced to enhance the transient performance of the VR. The proposed control method enables the VR to operate at a lower switching frequency in 250 KHz range for higher efficiency during steady state operation but respond fast accordingly to transient events when necessary. Compare to conventional method, the proposed control method requires less output capacitors by 30-40% and reduces the cost of VR significantly.
