Title

Active Transient Voltage Compensator Design For Vr Load Line Improvement

Abstract

Active transient voltage compensator (ATVC), only engaged in transient periods, was proposed to improve the VR load line and main VR can be optimized design with better efficiency which mainly handles the dc current. ATVC has reduced switching and conduction losses in extra converter due to the introduction of a transformer and it can also reduce the number of VR capacitors for required voltage tolerance. The compensation network delay times deteriorate the second voltage spike at high slew rate transient, especially in the high bandwidth controller. In this paper, combination of linear and adaptive nonlinear control is used to reduce the delay times of the compensation network. Finally a prototype of 3-Ch VR + ATVC was carried out on Intel motherboard and detailed experimental results are given. © 2006 IEEE.
