hi welcome to the pizza engineering channel in this video we are going to show how to design an
improvement of mppt based solar charge controller in matlab simulink software
before we start with our simulation i'd like to request if you're not yet part of our family

this is our system i'll just go through each component
we can get all the components from the browser
here we have our pv array these are the parameters
here we have our blocking diode generating and
here we have our capacitor is the value of our capacitor is the atmosphere didn't change anything
here i have another diode didn't change anything
here if our inductor is the value 10 to the power minus 3 here i have a capacitor 2 that's the value
and here i have our bit 3 let us set for the 8 200 capacity 50 system
here it goes to the signal to goes to the mvp solar charge controller to charge the battery
that's the battery parameters if you go there we can check from here we better observe algorithm
let's do the power pv power here i have our delay unit delay
minus the reference that certified will give the reference power and then it goes to the switching
note the switch
you can just follow everything there
here we have our voltage and our voltage reference
that goes to the unit delay that will give us our voltage
our reference voltage and goes to the switch
as you can follow follow everything then
from 0.6 to 0.4 output power if our b3 parameters there you have our state of charge
it is like it's minus 100 here we have our current in the ivf voltage
battery voltage
and there is your battery part and then you have other reference you can just follow as there
i mean gain and pin double generator depends on the field that you are using
is our pw m which is connected to the mosfet
here is our measurement
just change our
our simulation time
now we cannot you know it thinks everything is okay we can
as you can see just the part that the power output of our pvp array that's the same and
here we have our state of charge of the battery which is now exchanging was 50 now is going up
let's just open our graph you say the state of charge is going up means it's cr is is charging
let's see our
our current
the current is negative and here is our voltage
let's play around our solar addition let's increase our solar radiation
and the output structure increased as well yeah as you can see i've been increased
well let's keep on increasing forward you're playing around if you're good used
