Abstract: In V2 control, the direct feedback contains the information of the inductor current, the capacitor voltage, and the load current. In this paper, by separating the current feedbacks and the capacitor voltage feedback, an equivalent circuit of V2 control with ESR dominant output capacitor is proposed. The proposed equivalent circuit is based on the unified equivalent circuit of current mode controls. It is a completed frequency domain model for V2 control with a clear physical insight. V2 control can be interpreted as an advanced implementation of current mode control with a proportional voltage feedback and an additional load current feedback. The load current feedback dramatically reduces the output impedance of a current mode controlled converter. The model is extended to the enhanced V2 control. The proposed model is applicable to both variable frequency modulations and constant frequency modulations. The modeling results are verified by the Simplis simulation and the experimental results.
