Optimized implementation of a DC-DC power converter modeling and control strategy for efficient operation of a photovoltaic application

This paper describes a small signal model, voltage controller design and its implementation for a DC/DC converter in a PV(Photovoltaic) system. The detailed small signal model is proposed to design a voltage controller for the system. Based on the proposed small signal model, a voltage controller for the PV system is designed and tested with different internal resistances of the PV system. The designed voltage controller is validated through a DSP(Digital Signal Processor) based prototype PV system.
