Hi
i am doing a project in solar pv mppt with boost converter in matlab simulink. i have simulated solar PV mathematical model. i dont know which powergui is best to get the correct output. discrete i have chosen. but changing the sampling time the output value also changing. same in the case of a dc-dc boost converter. output of boost converter is changing while changing the sampling time. i have chosen 20kHZ for mosfet as switching frequency. what value should be used for powergui in discrete form.

Thanku

Thanku[/QUOT

the attachment wil show the difference in output for different sampling time for boost converter without changing the component values and switching frequency

Hi,
I have the same problem as you.
Can you please tell me how you chose the sample time of the powergui?
Thank you very muck.
