    I suppose that the "strong basic concepts" are the opposite of the "weak basic concepts". I would start with the basic operation of the inductor. If you don't have any calculus then this one is going to be tough, but the basic idea is that a voltage can be created from a changing current. If you change the current very slowly then there is almost no voltage generated. If you try to change it rapidly, like with an on/off switch, then you can generate large voltages. This, in a nutshell, is THE fundamental concept of the SMPS.
    Code ( (Unknown Language)):
    1.  
    2. V = L * di/dt
    3.  
    4. where V is the voltage across the inductor
    5.       L is the inductance
    6.       di/dt is the derivative or time rate of change of the current
    7.  
    8.

    Hi guilgan,

    Im a new member of this forum.Interested also in SMPS.
    I suggest to read first basic converter theory and familiarize wit the circuits construction.
