    Hi,
    In a centertapped (i.e. dual input) /single output step up transformer; does the inductance of the non-activated section of the primary winding affect in any way the inductance value of the activated input section?

    This question is most relevant when the centertap is used as the input to either section and the direction of current movement is controlled by power MOSFETs at either end of the winding.

    Any help with this is most appreciated.

    Thanks,

    Scott

    I think you need to provide a bit more detail.

    The short answer is no, the inductance is only affected by the coil and core materials you are asking the inductance of.

    However I think you are referring to a push pull drive to single ended output with perhaps a CT output transformer earthed at the CT?

    If one end of the dual primary winding is virtually or literally open circuit then it would not normally, there will be an induced voltage, but it depends if it has anywhere to go?.
