	abstract = {The multilevel multi-string inverter has gained much attention in recent years due to its advantages in lower switching loss, better electromagnetic compatibility, higher voltage capability, and lower harmonic distortion.\&nbsp; Solar Energy is one of the favorable renewable energy resources and the multilevel inverter has been proven to be one of the important enabling technologies in photovoltaic (PV) utilization.\&nbsp; As the number of levels increases, it is important to control more switches in parallel with their concurrent processing capability.\&nbsp; This paper proposes an IGBT clamped three phase nine levels photovoltaic inverter topology with a multicarrier dual reference pulse-width modulated (PWM) control scheme. \&nbsp;Four carrier waves of the fundamental frequency and different amplitudes are compared with two references (a sine wave and its opposite) for generating the control signals of the switches.\&nbsp; Some DC/DC boost converters are used to amplify the voltage produced by the photovoltaic generators. \&nbsp;Each of these converters is controlled by an MPPT algorithm in order to track the maximum power point of the GPV. \&nbsp;Results of simulation in Matlab environment are given and discussed.},
