hi welcome to the pizza engineering channel in this video we are going to simulate the
charging of a battery using a pv solar mppt charge controller based on the back converter
before we start our simulation if you are not yet part of our family
a lot of requests please subscribe to the channel share our content comment and like this video
this is our model all these components we got them from library browser and
we'll just go through introducing this is if our solar edition is our pv array
let me just organize the model
here we have our pc these are the parameters
the measurement
if our charge controller mppt
or duty cycle is common music operator
nif our gate the measurement this is location let's open our pv array one pv one model canadian
solar model these are the parameters and let's plot the output power the power output graph
is the capacitance capacitor the mosfet we didn't choose anything
our inductor the value there
capacitor everybody there
never b3 is the lord level is there the parameters if they're from
by selector it's elected if the voltage and the current you have ideal unit delay didn't
change anything then from there it goes to our charge controller mppt let's open our
entity here's our duty cycle instead of you can just follow the steps
uh
here we have our repeating sequence
and outcome
right
our charge controller that controls the gate of the old operation of back converter here with
our power output from the pv array now we can simulate and check the behavior of the system
as you can see that the voltage
the current is negative as the pv array is used to charge the battery
as you can see the battery is being charged
now let's just change the parameters to check the behavior let's reduce the solar irradiation
and see how much effective charge
as you can see the bit is charged if lower current because the pv array is
supplying less current always producing less than a normal
