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.

V = L * di/dt
 
where V is the voltage across the inductor
      L is the inductance
      di/dt is the derivative or time rate of change of the current

 

Hi All,

Thanks for your help....will start reading-up on this materials.

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.
