Plz. I need help because I dont know what is wrong with my simulation. The result of the output voltage is always zero. I wonder why and how to correct the error. Thanks alot ! I am quite anxious. The simulation file is concomitant. My version is 2019a. Thanks alot !!!!!

Hi Haotian Qiao,
If you check gate pulse to the IGBT, it is always ON, which means your source is always short-circuited, hence there is no voltage across source or load.
Also, what I observed is the solar module is not properly configured because open circuit voltage is also not appearing at the output.

Thanks alot, I am not so familiar with simulink and its models. I have changed to use Psim. But its really helpful of your answer. After I finish my paper, I will consider it again. Thanks!
