Design and control of a current source flyback inverter for decentralized grid-connected photovoltaic systems

This paper presents a new design and control strategy of the flyback inverter for decentralized grid-connected PV systems, in order to achieve high power density, high efficiency, and high power factor regulation. The design and control methodology which are investigated are aiming either to the achievement of a converter with the smallest possible volume for a given power or to the maximization of the power transfer that can be achieved for given converter parameters. The validation of the proposed design and control methodology will be confirmed by experimental results accomplished on a laboratory prototype
