Native AVP Control Method for Constant Output Impedance of DC Power Converters

A variety of different control methods have been reported to achieve adaptive voltage position (AVP). In this paper, a new control method NAVP (Native Adaptive Voltage Positioning) was proposed and implemented. It features good performances in phase-current sharing, transient response and DC output voltage regulation. Discussions about compensator design for this method is also included. Simulations results and silicon implementation of this control method verified the concept.
