theres a book  *-Timer/generator circuits manual-  by R Marston *
it covers 555 to xr2206 , LC , xtal ,pLL ,sine , square , triangle  ,saw and wave shaping. its a good book too ,read it a few times over the years . its available thru local library thru -inter loan*-...
there IS a charge.

R,
the hydro is a pretty good example , the least amount of i.p = higher eff.
the environment takes up the diff.    turbines DONT turn on their own do they?

POWER SUPPLIES ONLY** I dont recommend building or buying. Its YOUR MONEY!
Ive built similar in the past.
heres links to PS which are mobile. ALL using push pull. Enough info to get an understanding.

this is origin of on board PS = valve radio in the 40s using vibrator 50 - 100hz centre tap trans

open an old computer and no doubt theres TL494,TL594,KA7500,SG3525  these chips have 2 OR 1 output option for 1 or 2 transistors
basically these circs are all the same but diff power rates suited to requirements.
I still use 555 now and then , theres nothing wrong with them.**These circs are for those that want an independent PS.

stephen horvath patent has a push pull circ but drawn its inoperable. this is the correct hook up where the core itself triggers the 3055 base pins=self oscillating transformer.
sec Z is reflected back to pri otherwise itd burn
