High efficiency AC photovoltaic module: Efficiency or reduced number of components?

This paper presents the analysis of two AC photovoltaic modules: i) a flyback based, and ii) a full-bridge based. The comparative analysis takes into account the number of semiconductor components, such as switches and diodes, and the delivered power to the grid by each topology. The full-bridge based AC module has one of the highest component count among all the AC modules. In spite of it, it achieves high efficiency and performance. On the other hand the flyback based AC module has one of the fewest component count. So, the goal of the analysis carried out in this paper is to investigate whether it is possible to deliver more power to the grid, even with a higher component count.
