Abstract
Today’s Marine industries are undergoing transformation because of rapid growth of advancement in the field of automation. Shipping industries use hybrid propulsion systems to de-carbonize and orient the path towards zero emission. The renewable energy supply (RES) is utilized by reducing the dependence on imported conventional fossil fuels; greenhouse gas emissions produced by the usage of fossil fuels are reduced. Renewable green energy is used to generate power at the distribution level. Energy sources are distributed around the world. The utility's hybrid (wind/solar) power system has proven to be a reliable source of energy. In this article, PV and wind (hybrid) power used for marine applications with the reduction of fuel consumption is proposed. The hybrid buck boost converter used for regulating DC output voltage. A multi-level H bridge inverter between DC-DC converter and load provides the load's ac voltage requirement in hybrid systems. For a given output waveform quality, MLI topology provide lower THD and EMI output, higher efficiency and better output waveform. In order to design a multilevel inverter, a cascaded H-Bridge structure was adopted. PWM (Pulse Width Modulation) techniques enable the operation of Cascaded H Bridges to generate an approximate sine wave output from a multilayer inverter. To improve the hybrid system's performance, output of converter is supplied to the thirteen level H bridge inverter. This combination can maintain the appropriate voltage to load ratio. Voltage profile is improved by using H-bridge multilevel inverter. The proposed framework is re-enacted utilizing MATLAB/Simulink.
