Single-Phase Seven-Level Grid-Connected Inverter
for Photovoltaic System



I. INTRODUCTION
THE ever-increasing energy consumption, fossil fuels
soaring costs and exhaustible nature, and worsening
global environment have created a booming interest in renewable
energy generation systems, one of which is photovoltaic.
Such a system generates electricity by converting the Sun s energy
directly into electricity. Photovoltaic-generated energy can
be delivered to power system n ....etc

Abstract
When no transformer is used in a grid-connected photovoltaic
(PV) system, a galvanic connection between the grid and
the PV array exists. In these conditions, dangerous leakage currents
(common-mode currents) can appear through the stray capacitance
between the PV array and the ground. In order to avoid
these leakage currents, different inverter topologies that generate
no varying common-mode voltages, such as the half-bridge and
the bipolar pulsewidth modulation (PWM) full-bridge topologies,
have been proposed. The nee ....etc

Abstract:
A maximum power point tracking algorithm for single-stage converters connecting
photovoltaic panels to a single-phase grid is presented in this paper. The algorithm is
based on the processing of current and voltage low-frequency oscillations introduced in the
PV panels by the single-phase utility grid. The algorithm has been developed to allow an
array of PV modules to be connected to the grid by using a single-stage converter. This
simple structure yields higher efficiency and reliability when compared with standard sol ....etc

ABSTRACT:
There is a strong trend in the photovoltaic (PV) inverter technology to use transformer less topologies in order to acquire higher efficiencies combining with very low ground leakage current. In this paper a new topology, based on the H Bridge with a new AC bypass circuit ....etc
