| Description | This work was performed within the framework of the project “eSOLAR: Principle and control of high-efficiency Buck-Boost type Photovoltaic inverter” of the program “Bilateral and Multilateral Research & Technology Cooperation between Greece and China”, funded by the Operational Program “Competitiveness, Entrepreneurship and Innovation 2014-2020” (co-funded by the European Regional Development Fund) and managed by the General Secretariat of Research and Technology, Ministry of Education, Research, and Religious Affairs under the project eSOLAR/T7ΔKI-00066. | en |
| Content Summary | Single-phase transformerless photovoltaic (PV) inverters are based on unconventional power circuit topologies and are required to achieve very high efficiency and power quality over their entire operating range. Optimization techniques applied to conventional converter topologies need to be extended to cover these requirements. This paper proposes a PV inverter design optimization method for Aalborg-type transformerless PV inverters which integrates simulations in an optimization algorithm to maximize the inverter European efficiency, while abiding by the power quality limits set by relevant standards. According to it, the entire PV system, including the PV array, the PV inverter with its controller, and the grid are simulated in MATLAB-Simulink to estimate the inverter losses and output current distortion for design alternatives devised by the optimization algorithm. Design results obtained on an Aalborg-type transformerless PV inverter, indicate that its European efficiency can be maximized under different sets of constraints, while maintaining permissible output current quality at all power levels. | en |
