Grid Connected DC Voltage Control with MPPT by Buck/Boost Converter

N.M.Jothiswaroopan, A.R.M.Sasidhar

The project is about Grid Connected DC voltage Control with MPPT by Buck-Boost Converter. Solar Panel helps to sense both voltage and power ratings and uses MPPT Fuzzy control method for voltage control and regulation by operating both power and current as variables. It calculates temperature i.e., physical signal value. The scheme helps for satisfying the both forward and reverse mode of operation with Buck-Boost process based on the essential DC Voltage Level. Sinusoidal Pulse Width Modulation (SPWM) is used as pulses for inverter work. The switches of Boost Converter are operated in 120* mode of operation to control the short circuit across them. Duty cycle helps to control the current distortion by varying the frequency (in terms of time period) of a generated pulse. It helps to maintain constant voltage in DC Grid. Simulation work is used to verify the outputs. The software used is MATLAB.
