Re: shema za PWM
Ovo je isto to samo ima ograničenje struje

Ja sam si napravio ovu

da bi si smanjili struju dovoljna je i naj jednostavnija kao ova

Da li bi neko ovo mogao sastaviti?
The square wave pulse ratio determines the amount of current sent to the Generator
electrodes by the circuit of figure 5. If the ratio is low (1:1), very little current arrives at the
electrodes. So, very little hydrogen and oxygen are produced by the Generator. If the ratio is
high (10:1), maximum current reaches the electrodes and the Generator produces maximum
gas volume. Varying voltage input from a potentiometer connected via a 10K resistor to pin 3 of
component LM741 causes the circuit to vary the pulse ratio, and therefore controls the amount
of gases produced. The potentiometer shaft connects to the vehicle throttle linkage, enabling
control of gas volume in direct response to voltage changes correlating with rotation of the
potentiometer shaft in relation to throttle positioning. A trimming potentiometer connects pins
2 and 6 of component LM741, enabling precise adjustment of the throttle input signal. A
second trimming potentiometer connects pins 4 and 7 of component NE555, enabling precise
pulse width adjustment.
The electrode pairs of each Generator exhibit a unique frequency of electrical resonance at
which optimum gas volume is created. This frequency often varies considerably among
different Generators. Several factors determine resonance frequency such as: electrode size
and shape, Generator chamber size and shape, spacing between electrodes, coil parameters
and relative positioning, and pulse amplitude (voltage level). A trimming potentiometer
connected between pins 1 and 2 of component CD4069 allows the precise frequency to be
obtained. By selecting various combinations of dipswitch connections to a bank of four
capacitors, pulse frequency can be varied between approximately 8 KHz and 260 KHz.

Re: shema za PWM
a šta si ga toliko zakomplicirao, dal to ima svrhe za dry cell ?

Re: shema za PWM
Mislim da bi se sa takvom elektronikom moglo dosta igrati. Nije bas prijeko potrebno, ali ako se da napraviti ne bi bilo lose.joza888 je napisao/la:a šta si ga toliko zakomplicirao, dal to ima svrhe za dry cell ?

Re: shema za PWM
koja je najjednostavnija izvedba, molio bih shemu ali ako je to uopce potrebno jer dosta ljudi vozi bez toga i imaju dobar ucinak!! ?

Re: shema za PWM
ima li mozda neku ovu semu sa vrijednostima elemenata, ili ako neko moze da odredi velicine elemenata na ovoj slici. Hvala
