Hi,

I am giving 100V AC input to the board, but i am not connecting any load. I am running the code in Build 3 mode(both current and voltage loop closed),  initially switching is happening and it is boosting to 400v but after reaching 400V switching is not happening.what is the reason for why switching is not happening?

thanks

  • hi,

    If there is no load., the duty should be  very small,  or the frequency would be very high.  in order to limit the switch frequency, it should be worked in burst mode.

    please confirm if it works in burst mode.  or be protected for some reason.

    Hi,

    can you please explain what is burst mode.

    Thanks

    Hi, Yashawanth

    Burst mode is a kind of discontinous working mode. 

    It insert a short period time with stop working, in a longer period, to reduce the ernergy transfered to output side.

    Thanks.

    Hi sir,

    But without load also it should regulate to 400V? , i am giving input voltage according specification.

    Thanks

    Hi, yashwanth

    The output capacitor will keep the the voltage in the stopping time. 

    thanks.
