Distributed Mppt Based Moduler Cascaded H-Bridge Multilevel Inverter



This Project Presents Distributed MPPT Based Modular Cascaded H-Bridge Multilevel Inverter. The Modular Cascaded Multilevel Topology Helps To Improve The Efficiency And Flexibility Of PV Systems. The SPWM technique based PWM inverter is help full in making the switching pulse with better output. A new modulation method called trapezoidal triangular multi carrier (TTMC) SPWM is implemented and compared with other methods. This new modulation method gives advantages in multilevel inverter to minimize the percentage of total harmonic distortion (THD) and to increase the output voltage. To realize better utilization of PV modules and maximize the solar energy extraction, a Distributed Maximum Power Point Tracking control scheme is applied to the three phase multilevel inverters. The power generated by the inverter is delivered to power network, so the utility grid. The proposed system is simulated using MATLAB.
