CC CV control with Frequency modulation

Hello, I would like to know how to linked two control together, the control including constant current, constant voltage CCCV for battery with variable frequency modulation for switches (inverter). Thanks

any help?

Hi @SALAH alatai

It's a little complicated without the math, model, MATLAB code, Simulink file. If CC and CV are transfer functions, then "linking" them in series is pretty much like building Lego bricks.

@Sam Chak ok like this example on mathworks

This one looks like physical represention of the LLC Converter.

Can you extract the mathematical models from the Simulink model?

@Sam Chak unfortunately I do not know how to extract the mathematical models

Hi @SALAH alatai

Try following the examples on using these functions to extract the mathematical model.

Once you have the model, you will have an arsenal of design tools in Control System Toolbox to help you...

@Sam Chak thanks for your response but seems difficult to understand.
