Fuzzy logic control for a grid-connected PV array through Z-source-inverter using maximum constant boost control method

Maximum Constant Boost Control of SL-Z-Source Inverter

This paper explores Switched Inductor (SL) Zsource inverter which adjusts the voltage and have application in Fuel cells (FCs) which have achieved global attention as an alternative power source for hybrid electric vehicles (HEVs). The proposed inverter uses inductor and capacitor circuit to join the source and load circuit. On comparing with the initial Z-source inverter, the explored circuit ...

A New Control Method for Grid-Connected PV System Based on Quasi-Z-Source Cascaded Multilevel Inverter Using Evolutionary Algorithm

Received Aug 27, 2014 Revised Dec 2, 2014 Accepted Dec 25, 2014 In this paper, a new control method for quasi-Z-source cascaded multilevel inverter based grid-connected photovoltaic (PV) system is proposed. The proposed method is capable of boosting the PV array voltage to a higher level and solves the imbalance problem of DC-link voltage in traditional cascaded H-bridge inverters. The proposed...

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...
