Project 1 - Loss calculation for a DC/DC converter-MATLAB

Input parameters:

load resistance:

L(inductor):

Capacitor:

Pulse generator:

outputs graph:

1. Diode volage and current:

From the graph we can see that diode withstand voltage and current should be 35V and 20A. So we have chosen the diode MBR2050CT with specifications:

2. Mosfet voltage and current:

The mofet chosen to withstand 35V, 20A is NTD5867NL

3. Inductor current and input voltage:

The inductor choosen for this is:

The capacitance model choosen is:

Output voltage and current graph:

The desired voltage and current at output was: 35V and 3A, but we got 33.5V and 2.8A. We can use a PID controller to improve the performance of the system.

hence we can see that for this system i have calculated all the losses and efficiency which is 98.2%.
