Abstract
In this system, we use a Multi-level inverter to power an electric boat propulsion system powered by PV Panels. The eleven-level inverter is used to supply power to multi-level switching cells of the inverter which drives the AC motor.It is an Asymmetrical Cascaded H-bridge Inverter. A Multi Carrier PWM signal is given based on Multi Carrier Modulation Technique to obtain equal steps in the eleven-level output. A Sepic converter is used which allows adjustment of a range of DC voltages to provide a constant voltage output. It is a DC converter that basically regulates the voltage from the PV Panel and all subtractive and additive combinations of DC input levels can be obtained in the output signal. ANN controller is applied forming an efficient closed loop system that is involved in the elimination of harmonics in PWM inverters.It reduces the overall Total Harmonic distortion. The system consists of optimized PI based MPPT that ensures efficient PV power generation.
