| Abstract |
This paper presents the design and the control strategy of a new single stage high frequency simplified converter topology for decentralized grid-connected PV systems. The proposed converter is based on the flyback converter topology operating in the discontinuous conduction mode where it behaves as a current source. Its main advantages are the very high power density and the high efficiency, due to its simple structure, as well the high power factor regulation that is achieved. A design methodology is developed aiming the achievement of a converter with the smallest possible volume for a given power. PSPICE simulation results will be exhibited, highlighting the advantages of the proposed converter topology. The validation of the design and control methodology is also confirmed by experimental results accomplished on a100 W laboratory prototype. |
