Hi Fam and Friends, Im really bad in power electronics as i needed you guys to help me to explain the resulted graph that I've gotten from my simulink. PLEASE help !
Hi guys could u guys please help me explain what is happening on this 3 graphs. I am an electrical student and just to be honest i am not a smart student but I'm willing to learn. Please do help me.Ive got my simulation i managed to generate perfect sin wave but i just couldn't explain on the graphs i simulated.

Hey nathan,
The first graph represents the source voltage:
- V_source = 300*sin(ωt); where ω = 2π*50 for this case
The second graph represents output of diode bridge rectifier, without a dc-link capacitor (or any other filter):
- V_dc = abs(300*sin(2ωt))
The third graph represents output of square wave inverter.
- V_inverter = -Vdc for 0 < ωt < π
- V_inverter = +Vdc for π < ωt < 2π
However, since the dc-voltages are not filtered, and contains pulsating voltages, the waveform appears sinusoidal.
Hope this helps.
A suggestion: The model you are trying to simulate will perform better with a smaller time step for simulation.
Hi Darshan pandit Was wondering if you have an email that I could contact with. As I've had some struggle as well. Thank you for the explanation. It helps a lot
Kind regards Nathan
Sure Nathan.
Edit: Glad to know that my information helped. For future readers of this post, I would encourage to contact via following email: support@mathworks.com
Have a great day.
