Efficiency improvement method for two-stage server power by auto-tuning of bus voltage based upon new on-line switching frequency tracking technique

An efficiency improvement method for two-stage server power by auto-tuning of bus voltage based upon new on-line switching frequency tracking technique is presented in this paper. The basic idea is to let the switching frequency to track the resonant frequency of converter to either reduce the turn-off losses or circulating losses of converter, and thereby… (More)
