A HARMONIC-FREE CURRENT-LINK AC TO AC POWER SUPPLY:DYNAMIC ANALYSIS AND DESIGN

In this paper, the dynamic analysis and design of an AC to AC power supply with DC current link is presented Despite many advantages of such a structure, its application in fixed frequency power supplies has received very little attention in the literature Different issues related to dynamic analysis of the proposed system are considered These include a simple averaging technique for modeling switching function generators, the concept of Internal Model Controllers, and necessary condition to avoid multiple crossing in ramp comparison methods Theoretical and experimental results obtained from a DSP-based laboratory type setup are presented.
