Buck Converter In MATLAB

Buck Converter In MATLAB ideas and topics that we have worked previously are shared below stay in touch with phdservices.org to get customized project solution. Building and simulating a buck converter is a both intriguing and challenging process that involves several important procedures. To carry out this process using MATLAB, we provide a detailed instruction in a step-by-step manner, along with an instance of MATLAB script:

Step 1: Specify the Elements

Various elements such as an input voltage source, a load resistor, a capacitor, an inductor, a diode, and a switch (such as transistor) are generally encompassed in the buck converter.

Step 2: Develop the MATLAB Script

As a means to simulate a buck converter, a simple instance of a MATLAB script is offered by us:

% Parameters

Vin = 24;            % Input voltage (V)

Vout = 12;           % Desired output voltage (V)

R = 10;              % Load resistance (Ohms)

L = 1e-3;            % Inductance (H)

C = 100e-6;          % Capacitance (F)

f = 50e3;            % Switching frequency (Hz)

D = Vout / Vin;      % Duty cycle

T = 1 / f;           % Switching period (s)

dt = T / 100;        % Time step for simulation

% Time vector

t = 0:dt:0.1;        % Simulate for 0.1 seconds

% Initialize variables

V_L = zeros(size(t));  % Inductor voltage

I_L = zeros(size(t));  % Inductor current

V_C = zeros(size(t));  % Capacitor voltage

I_C = zeros(size(t));  % Capacitor current

I_R = zeros(size(t));  % Load current

V_out = zeros(size(t));% Output voltage

% Simulation loop

for i = 2:length(t)

if mod(t(i), T) < D * T

V_L(i) = Vin – V_C(i-1); % Switch is ON

else

V_L(i) = -V_C(i-1);      % Switch is OFF

end

I_L(i) = I_L(i-1) + (V_L(i) / L) * dt;  % Inductor current

V_C(i) = V_C(i-1) + (I_L(i) – I_C(i-1)) * dt / C; % Capacitor voltage

I_C(i) = V_C(i) / R;  % Capacitor current

V_out(i) = V_C(i);    % Output voltage

end

% Plot results

Step 3: Simulate and Examine

In MATLAB, we plan to execute the script. Periodically, the inductor current, inductor voltage, and output voltage must be displayed by the resulting plots. For validating the functionality of the buck converter and interpreting its activity, these plots are very useful.

Step 4: Enhance and Develop

Through adapting parameters such as the switching frequency, capacitance, and inductance, we intend to enhance the simulation even more. To create the simulation in a highly precise manner, several practical components have to be included, like the resistance of the inductor and the equivalent series resistance (ESR) of the capacitor.
