Abstract :
The aim of this work is to design and simulate low cost, portable efficient solar power inverter for standalone applications using MATLAB SIMULINK and MSP430 Micro controller. The designed expected output is 300 W, 230 V pure sine wave signal. The incremental conductance based Maximum Power Point Technique (MPPT) algorithm has been implemented using synchronous buck converter at the first stage. Since this project is designed for standalone applications, lead acid battery is selected, which has maximum charge storage capacity of 100 Ampere-Hour and charge/discharge rating of 10 i.e. 100 Ah and C/10, 12 V Lead Acid). Half bridge dc-dc converter is designed to boost the battery voltage from 14.5 V to 400 V DC. The final stage of the project is single phase full bridge inverter which produces the distorted quasi sine wave signal as output, which is later filtered to remove unwanted harmonics using designed LC low pass filter. Since this project is designed for low power applications, MOSFET is used as the switch in all the power circuit stages. The control strategy here is designed and accomplished by employing MSP-430F5132 micro controller which is user friendly and cost effective solution.
