sir, im trying to run ILPFC_VALLEY_SWITCHING_ F28004x example in my F280049C launchpad. Can i use my buck converter plant by using single phase PFC option and disabling valley switching option in main.cfg(powersuite) file.. is that possible to change frequency and voltage in main.cfg(powersuite) file..

    Hi SOWMIYA,

    No, you can not use single phase PFC option while at the same time disabling valley switching. The powerSUITE is set to enabling single phase together with valley switching.

    Thank you sir,

            I need to find transfer function for my buck converter plant .. is there any seperate development kit is available... or else can i use open loop option or closed current loop option with dc input in valley switching model ...is that the development kit and solution adaptor available in sdk software are meant for particular board represented in that model?? It wonn.t  consider a plant as a black box ?... i need to do compensator design for various converters having single switch... is there any other example or option available

    Hi SOWMIYA,

    There are too many questions to answer at one time.

    Are you looking for the transfer function of general buck converter? this link has relative information: www.ti.com/.../sprabt6.pdf

    is that the development kit and solution adaptor available in sdk software are meant for particular board represented in that model??
    Yes, they are for particular board.

    or else can i use open loop option or closed current loop option with dc input in valley switching model?
    I don't know why you need valley switching model. But you can run valley switching project under open loop and closed loop. DC input is also ok, but it has to be aligned with the user guide and has to be single phase.

    It wonn.t consider a plant as a black box ?
    Some of our design are model based, some are like black boxes.
