This question may seem like a trivial one, but anyway i want to ask out of curiosity.
Who invented all these power supply topologies like
BUCK,BOOST,FLYBACK,PUSHPULL,FORWARD.......
 

I know it wasn't Buckeroo Odgers, Booster Hupp, the Bipolar Sisters, Fred Ward or Khan Vhurter ;). we're prttery sure , weren't any of them.

I wish I had nickel for every time that I though I invented a design, only to find out someout else already did it.
Like the Emitter Coupled Oscillator with a capacitive load....

Good luck in your research.

What I can tell you that electro-mechanical vibrators, which are the basis for pushpull technology, have been used since the late 1930s to supply high voltage to the plates of vacuum tubes from the 6 volt auto batteries used at the time.

nobody has ever claimed the ones you spoke of........the only "standard" converter that anybody has ever claimed is the Cuk converter...which is "invented" by Slobodan Cuk.......though many have invented it "accidentally " by taking a sepic and then swapping the output side inductor and diode round.
 

Even the standard gasoline engine points ignition system, or magneto is a type of flyback supply.

Most of these things have been around long before the electronic age in one form or another.
They are now so old I doubt if there ever was a single inventor.

Michael Faraday was messing around with this stuff almost 200 years ago.
 

I once spoke with Slobodan Cuk and asked if he knew how to regulate a ramp from 2kV to -1.5kV without shielding or EMI from 12Vdc using PWM input. He wanted the business but could not offer a conceptual solution other than his Cuk topology. In the end, nothing Switched mode could possibly work. It had to be a resonant step-up transformer to be EMI quiet and very low cost.
 

Here is a really nice example of a mechanical PWM switch mode power supply.
Voltage regulated and current limited, with a mechanical output diode.
State of the art in 1958. What more could you possibly want ?

Right, the basic topologies have good analogies to the mechanical world.

The hydraulic ram is a water pump that can 'boost' water up-hill with exactly the same operation as a standard 'boost converter'.

yes a flyback converter is like "bucketing" water from a pond into a tank.
If in CCM, then you dont empty the bucket completely into the tank, but still have a bit in there when you dip it back into the pond to refill it.
Of course, DCM flyback is when you do it but empty the bucket each time.
