A Dual-Function Power Decoupling Circuit for Single-Stage Grid-Connected PV Inverter

Photovoltaic energy is one of the most widespread renewable sources of electrical energy. At the heart of the power conversion system is the grid-connected interface converter based on power electronics. Single-stage systems offer higher efficiency and lower cost and size. However, they suffer from a reduced operating range due to the effects of irradiation and temperature. In addition, especially...
