Boost 12 V lead acid to higher values, like ca. 60V (+- 30) for amplifier...How?
"home" amplifiers are relatively easy to find. A simililar amp can be built from available (velleman) kits, or from discrete components. But for portable use (on the bicycle, or car) , with one, or max. two 12 V batteries, only ready made car amps are available.
The only thing between the choice of using stuff I already have or buying car sound system components is the power required...
Which would mean there is a circuit inside the car amplifier boosting the battery voltage...
Can anyone suggest a simple circuit or easily available gadget to boost the 12 V car battery voltage to the required +- 9 up to +- 40 V required for the variation of designs available.
I am thinking of using (X2) the 200 W Velleman kit (+- 30 V) or the TDA 7294 chip (+- 40 V) for my bike amp, but would also like to know how to boost to arbitrary values (like, 17, or +- 21V) (for understanding).
Of course, not just voltage, but also power is needed here!
