How can I bulid Matlab/Simulink Model for Input Ripple Current Analysis

Hello I'm stater please give me a reason.Hello, is anyone there? I need help. Does anyone know how to model a graph like this? I need information about Interleaved Buck Converter.

Hello Naphat,

I understand you want to build a model for Input ripple current analysis and want to know about interleaved buck converter.

NOTE: This package is not supported and maintained by MathWorks.

I'm attaching an article for the same: https://www.mathworks.com/matlabcentral/fileexchange/40249-interleaved-buck-converter

By any chance if you just want to plot that graph alone, you can leverage the help of plot function and can plot the graph, I'm attaching a sample code for the same:

% Angle values
theta = linspace(0, pi, 100);

% Calculate X and Y coordinates of the semicircle
radius1 = 0.5;
radius2 = 0.25;

x = radius1 * cos(theta) + radius1; % adding raduis to shift the center towards right on X-axis.
y = radius1 * sin(theta);
x1 = radius2 * cos(theta) + radius2;
y1 = radius2 * sin(theta);
x2 = radius2 * cos(theta) + radius1 + radius2;
y2 = radius2 * sin(theta);

% Plot the semicircle
plot(x, y);
hold on;
plot(x1, y1);
plot(x2,y2);
xlim([0, 1]); % Set x-axis limits
axis equal; % Set equal aspect ratio
xlabel('Duty Cycle');
ylabel('Normalized C in RMS Current');
grid on;

Continue the same for the other semicircles.

Hope this helps you!
