Abstract: A novel quasi-two-stage multifunctional inverter (QMFI) for photovoltaic (PV) applications is proposed in this article. With the help of the quasi-two-stage architecture, part of active power can be directly transferred from PV arrays to the grid or load within a single power conversion stage and hence improve the efficiency.
In this study, a two-stage grid-connected inverter is proposed for photovoltaic (PV) systems. The proposed system consist of a single-ended primary-inductor converter (SEPIC) converter which tracks the maximum power point of the PV system and a three-phase voltage source inverter (VSI) with LCL filter to export the PV supplied energy to the grid.
The inverters are widely used in renewable energy generation for their high efficiency and flexible control, such as photovoltaic (PV) power systems , , adjustable speed drive systems , wind energy systems , SVG (Static Var Generator, SVG) and APF (Active Power Filter, APF).
This study introduces a new topology for a single-phase photovoltaic (PV) grid connection. This suggested topology comprises two cascaded stages linked by a high-frequency transformer. In the first stage, a new buck–boost inverter with one energy storage is implemented.
Buck–boost DC/AC inversion, MPPT and low grid current injection can be implemented effectively. This study introduces a new topology for a single-phase photovoltaic (PV) grid connection. This suggested topology comprises two cascaded stages linked by a high-frequency transformer.
The second stage comprises a rectifier-inverter system which converts the high square wave voltage to the grid sinusoidal voltage. The two stages are linked together using a HFT. It also presents the whole control system that gives the switching signals to the system’s switches.
