Implementation of Multilevel Inverter Using Mppt Based Sliding Mode Control for Pv Cell

In this project photovoltaic array is used as source. The photovoltaic energy is used to feed the inverter through the step up converter. The output for solar module is connected to the battery. So the supply is given continuously by the battery to the system. The output of the solar may vary due to the radiation and will affect the battery. So the lifetime of battery is reduced. It is necessary to protect the battery from the non-linear solar energy, charge controller is used. In order to track maximum power, sliding mode controller is used. In the step up converter a new method is used. The new step-up converter consists of coupled inductor and fixed capacitor. The voltage stress of active switch is being reduced by clamp capacitor. The output of the new topology of dc-dc converter is given to hybrid multilevel inverter which consists of reduced number of switches. The overall system is simulated using MATLAB prototype of the proposed system is developed and output is verified with simulation results.
