DC/AC Conversion Topologies for Photovoltaic Applications

Authors

Alaa A Ismail,Amgad A El-Deib

Published Date

The evolution of DC/AC conversion configurations for Photovoltaic (PV) applications started from the central inverter, string inverter, DC optimizer with central inverter to the microinverter. The evaluation of each configuration efficiency is a main concern due to the rising dependence on PV power plants. Besides, the fact that uneven solar irradiance levels and modules mismatch play an important role in defining the system efficiency. This paper compared the efficiency of the DC/AC conversion configurations: the string inverter, the DC optimizer and the microinverter. The efficiency was estimated based on the maximum power point tracking efficiency, power electronics stage efficiency and cable losses, where all of them were combined to estimate the configuration efficiency. SIMULINK was used to model each configuration and estimate the efficiency. The model main input was the solar irradiance of different …

Photovoltaic (PV) systems are becoming an integral part of the zero net energy PV building integrated systems. Extracting the maximum power with highest system efficiency is a major challenge in PV grid connected systems. This work presents the development of a two-stage PV grid connected microinverter. The microinverter topology is based on using a DC-DC converter with high frequency transformer for the maximum power point tracking stage. Two topologies were compared, the two-switch flyback and boost flyback in terms of duty operating range, transformer turns ratio and components sizing. Simulations have proven an efficient tracking of the PV maximum power and DC link voltage set point. Hardware comparison between the two topologies was done based on the selection of the MOSFETs, diodes, and the transformer. The components selection was based on the power losses, cost, and the size. The …
