An Improved Control Strategy for A Single-Phase Non-Isolated Photovoltaic Grid-Tied Inverter
Objective
Main objective of this project is to reduce the volume, weight, and cost of the new inverter.
Abstract
In this project, a single-phase non-isolated inverter is proposed, which can handle the problem of the leakage current and the double-frequency power oscillation simultaneously. The presented inverter allows the neutral line of the AC grid directly connected to the negative terminal of the PV panel so that the leakage current is completely eliminated. Besides, based on a power decoupling method, the double-frequency power oscillation on the DC side can be suppressed without additional passive components.
The Matlab/Simulink model of the inverter is established and the influence of each parameter on its stability is analyzed in detail, and then an improved control strategy is proposed to reduce the inductance of the internal inductor. The effectiveness of the improved control strategy is verified by simulation in MATLAB/SIMULINK.
Keywords: single-phase non-isolated inverter, leakage current, double-frequency power oscillation, PV panel.
