A New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...

Design and Implementation of Predictive Current Controller for Photovoltaic Grid-Tie Inverter

This paper presents simplified predictive current controller for 3-ph PWM voltage source inverter connected to the utility grid via filter inductance. By controlling inductance voltage drop, the inverter voltage and hence the injected current can be controlled. The proposed predictive control technique operates with constant switching frequency using space-vector modulation (SVM). In each switc...

Development of 10 kW Three - Phase Grid Connected Inverter

In this paper, modeling, simulation and experimental study of a 10 kW three-phase grid connected inverter are presented. The mathematical model of the system is derived, and characteristic curves of the system are obtained in MATLAB with m-file for various switching frequencies, dc-link voltages and filter inductance values. The curves are used for parameter selection of three-phase grid connec...

Fuzzy Based Switched Boost Inverter for Microgrid Applications

Renewable energy sources (RES) place main role in present days to generate power. The Switched Boost Inverter is a single stage dc-ac power converter, whose output voltage can be either greater or less than its input dc voltage. This converter can supply both dc and ac loads, simultaneously, which makes it suitable for micro grid applications. Also, this converter allows shoot-through of the in...
