Abstract

A stability analysis of constant frequency current mode power converters is presented. A current mode control method that overcomes the limited duty cycle range of stability is introduced. The authors present the application of the control method to half bridge and full bridge converters, and describe an improved performance uninterruptible power supply (UPS) based on the method. The UPS has only one power transformer and one power transistor bridge. The authors present detailed experimental results which confirm the advantages of the circuits
