Integrating a multilevel inverter with the grid provides advantages in high-power and high-voltage applications, including reduced harmonic distortion without a transformer. This paper presents the implementation of Sorted stair-case modulation (SSCM) and Sorted Phase disposition (SPD) Pulse Width Modulation (PWM) techniques for a Grid-Tied Cascaded H-Bridge (CHB) multilevel inverter featuring single-stage power conversion. SSCM and SPD PWM techniques are used to track the MPPT of each PV panel under uniform and non-uniform irradiation conditions if the PV panels are connected to the inverter's input terminals. A centralized current controller has been designed for the Grid-tied multilevel inverter system. Furthermore, a simulation has been developed to compare the power quality of the grid current and voltage between SSCM and SPD-PWM.
