  • Abstract
    In V2 control, the direct feedback contains the information of both state variables. In this paper, by separating current feedback and capacitor voltage feedback, an equivalent circuit of V2 control based on the equivalent circuit of current mode control is proposed. The proposed equivalent circuit provides a clear physical insight of V2 control. V2 control can be interpreted as an implementation of current mode control with direct voltage feedback and load current feedback. The load current feedback dramatically reduces the output impedance. The model is extended to enhanced V2 control. The proposed equivalent circuit model is applicable to both variable frequency modulation and constant frequency modulation. The modeling results are verified by using Simplis simulation and experimental results.
