This research presents the study of an AC photovoltaic module, based on a full-bridge DC/DC converter with phase shift controller and soft switching technique that requires a simple controller. It has a high component count, although high efficiency and performance. In this study a comparison is made with one of the topologies with lower component count, based on a flyback converter. The goal of this study is to prove that even with a higher number of components the full bridge-based converter has better and higher efficiency and provides more energy to the grid.

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.

“…4] can be determined using the fact that the average voltage across over a switching period is zero. Noting that the average voltage across during is equal to the grid voltage during th switching interval, yields the following: (17) Substituting the value of from (17) in (14)- (16), yields the initial values of the state variables for the subsequent freewheeling state. When the switch is turned OFF, and the diode is not conducting , the governing state equations are (18) Solution of (18) is similar to the one obtained for turn ON condition of except for which is zero during the freewheeling interval (19) Substituting the value of in the solution of (19) gives the value of state variables at the end of the th switching cycle which are also the initial values of the subsequent switching cycle.…”

Abstract-This paper proposes a high performance, single-stage inverter topology for grid connected PV systems. The proposed configuration can not only boost the usually low photovoltaic (PV) array voltage, but can also convert the solar dc power into high quality ac power for feeding into the grid, while tracking the maximum power from the PV array. Total harmonic distortion of the current, fed into the grid, is restricted as per the IEEE-519 standard. The proposed topology has several desirable features such as better utilization of the PV array, higher efficiency, low cost and compact size. Further, due to the very nature of the proposed topology, the PV array appears as a floating source to the grid, thereby enhancing the overall safety of the system. A survey of the existing topologies, suitable for single-stage, grid connected PV applications, is carried out and a detailed comparison with the proposed topology is presented. A complete steady-state analysis, including the design procedure and expressions for peak device stresses, is included. Necessary condition on the modulation index " " for sinusoidal pulsewidth modulated control of the proposed inverter topology has also been derived for discontinuous conduction mode operation. All the analytical, simulation and experimental results are presented.
