- In this video, i have explained the MATLAB simulation of a bi-directional battery circuit using buck/boost converter. During battery charging the circuit works as buck converter and during dis charge it works as a boost converter. I have also explained the current controller used in the simulation.
Feel free to post your doubts in the comment section. For doubt clarification you can contact me at ashacademy01@gmail.com.

Very nice lectures, please do on complete gate driver circuit
thanks a lot ,it was very much helpful
great video....loved it
Sir if i have to put pv array application as a dc source input to charge and discharge a battery then what are the perimeters (mathematical modelling) required for pv array for this battery using buck-boost !
Thank you for the presentation . Please how are you determinate the parameters of your PI controller?
Thanks for the video. It has enlightened me.
You're welcome
Great God, you are updating again. You can do a bidirectional DCDC voltage and current control.
Sir please make video on battery charging and discharging using pv
Can we call this battery management system
Could you please post the reference paper used for this? I need it for the controller design.
👍👍👍 nice bro
Please one request do a video closed loop svpwm for motor application
How to find the values of PI controller
Good job.... please could you do simulation about single phase parallel inverter for microgrid ?
Can you please do simulations on MATLAB program for control circuits for Power electronics
For those who get the nagetive current results, just check if your scope observes Ibat or Ibat1. should be Ibat.
Correct
THANK YOU FOR SHARING OF WORK.SIR CAN U DO PROJECTS FOR PAYMENT
Can you simulate clossed loop three phase thyristor based rectifier... It will helpfull for my project
Can you explain to me how you know the ripple current and voltage?
Sir can you please tell me how you calculate the value for PI controller..?
This is for buck and boost both.???
merci
i am designing Bi-directional converter with input voltage of 200V. Sir can you please suggest the values of Kp and Ki in this case?
Sorry, sir. I have a question. In calculating converter capacitance(C), I calculate capacitance(C) it's 208 uF, not 20 uF. Is my calculation error?
right
Not displaying SOC and battery voltage on display in MATLAB 2019b
Please help me out
Sir I need calculations for solar and wind connected with battery and load (variable). Please suggest some paper or guide me to calculate all values
Sir can you make a video on pv battery based bidirectional converter controller for voltage control on dc link bus.
Hi sir I am getting output Ibat in 300 and above with reference value of 30 what is reason for this sir can you tell me please
how is vripple and iripple calculated? is there any standards to follow?
Designers choice based on the application. As a thumb rule i took the values
im getting negative current in my ibat1
i tried diffent switching also but not changing
you can share the model at my email
thanks for sharing ur work, how to find Vripple and I ripple?
how to find the values of p PI and the value of limitations 0 - 0.95?
Vripple, i ripple are designer's choice, there are some thumb rules, based on that i chose values.
PI tuning include many things, cant just explain it here.
set duty equal to 1 make the switch always ON, and circuit will not work properly. so i chose a value less than 1, that is 0.95
@@TechSimulator could you pls send me the thumb rules and the steps to tune
@@TechSimulator hello sir , please can you check your email address I have sent you my query but you didn't reply. Please I need your assistance.
sir , you have used Constant current charging method but can you please also make video of CC-CV charging, you PI values of CC controller are highly efficient and fast.thanks
will try
Sir, how to find I ripple and V ripple for calaculaion
why you add RC in parallel with Voltage source ?
not required, since it is a stiff voltage source. but in practical scenario, we need to have bus capacitacne in either side. so i put, RC, and R is the esr of cap
In my model if I put constant value as 30 in Ibat1 in display it shows -30 and voltage remains same when I put -30 as constant it displays 30 in Ibat1 voltage starts reducing can you tell me what's the problem in my model?
Pls share you model at my email id
The battery notations are reversed. In control logic, Ibat is used and while scoping the response Ibat1 is used, that's why it is showing negative.
@@yangyadatta not clear please help me to clear out the problem, I am also facing the same issue.
@@yangyadatta what is Ibat1.?
can u plz tell me?
WHY switching frequency 5kHz
Sir I go negative value of current while applying the loop ,please help me for the same.
Hi i also got the same result, did you fix it? if yes how? and whats the problem?
Sir, can you do with Bidirectional Quadratic topology?
will try to make
How to tune pi controller
Hello Sir, I’m getting Ibat= 1518, which is different from the reference value which is 30 A.
set dc voltage to 800v
my dear I simulated same your project but don't obtain same your result
you can contact me at my email
Bonjour Wissam nchl tkouni bi5yr, est ce que tu as avancée en peu pour ce type de convertisseur, je travaille sur le meme convertisseur ...
The calculation of the capacitor gives 200 µF can you please verify
Can u send the video on battery charging with dc dc bidirectional converter using solar
what exactly you are asking? where the battery discharges to?
@@TechSimulator I want model on pv system with battery storage using bidirectional dc dc buck boost converter
@@minakshisingh9571 Hey, did you make that model? i'm trying to do the same...
Minak, were you able to do it using solar? If so, could you please support me to do the same?
I did exactly as you did, yet when I ran the simulation, different results are coming. Help
mail
Can this be called as battery management system
No
Can you do it with MPPT ?
where i should discharge the battery?
@@TechSimulator connect it to output of dc boost converter
can u pls suggest something
Pla share ur model at ashacademy01@gmail.com
Sir can you send report for this simulation
sorry, i dont have
Why 800V and 360V...??
I chose some random numbers. U can choose whatever u want
my ibat is going 3500
How can we use this model to connect battery with grid ??
will upload the video soon
