Hi everyone,
I created an average model of a noninverting buck-boost converter with MPPT to make sure i have the maximum power at the output. When i run my program, everything goes fine until 10 ms. After that my voltage starts to drop drastically and also my output power drops. Also when i change G2 to 1000 (standard value 500), my program does not do what I would expect. When the irradiance rises, the output power should rise too. I think my conversion (diode and mosfet to current and voltage source) is not correct. Can someone give me something to look closer to, or does anyone knows a solution? I would like to thank you in advance.
I think the conversion (DIODE and MOSFET to current and voltage source) is not correct. but you can to the another way for solution
Alaa Hussein Ali, Do you know a book that contains this topic? I would like to study this topic, but i can't seem to find a good book about it. My preferred languages would be (English, Dutch, French and German). But it can also be a book in another language. Thank you for your response.
A frequent problem faced by researchers is incorrect understanding of what they are trying to do. Sometimes they impose inconsistent conditions on the behaviour of their circuit, imagining it can create or annihilate energy. There is no known way to do this! Treat the circuit initially as a black box and define the input and ouput. In real life output = input x efficiency and efficiency should be well over 90%. If this equation doesn't balance then your understanding needs to be addressed first, and only then can you go into your circuit to see what is happening. Best wishes with your research!
