These do not allow for fluctuating and "undersized" power and voltage, but my humble pulse charger does. |

2" X 4" in size |
|
| This patent pending baby is based on a pulse charging technique similar to John Bedini’s devices, but does not necessitate any timing adjustment. | ||

How it works |
||
The
charger uses a step-charging section (left) to build up “high” voltage on
an intermediate storage capacitor. An order of magnitude is x 2 the charged
battery nominal voltage.
The discharge-on-voltage-threshold section (right) triggers discharge of the cap into the battery as soon as the predetermined “high” voltage has built up.

Properties The
charger does not care fluctuating input (e.g. solar panel) thanks to the DC/DC cap charging technique that
uses a step-up, inductive converter. What
will change is the time interval between cap discharges into the
battery. Here
is a typical scope shot of the capacitor voltage waveform: the source
was a small 7.5 volt rated solar panel, and the battery a small NiMH 8.4
volt rated battery. The
threshold voltage (25 volt) is indicated by the arrow.
The
meter shows the battery near maximum voltage, 9.25 volt.

Overunity or not overunity ? The
inventor does not claim over-unity behaviour despite the similarity with
John Bedini’s description of pulse charging, but ·
The charger shows abnormally better than expected performance vs. textbook theory (charge or energy switched through capacitor) ·
It works even better if normal inductors are
substituted a “Caduceus coil” with ferrite core
