Appears to be overunity Cicuit

This is a typical impedance converter.
The bulb will not burn on a 12 Volt battery directly, as the
filament resistance of the bulb is too high, so
it needs higher voltage to start burning, but lower current then.

It is some kind of resonance step charging for the output cap.

Would be good,if you could post the waveform.
Also the output cap would charge faster,
if you use a real brigde rectifier with 4 fast diodes !

Now please again post the voltage at the bulb load
and the current through it.

Was 36.6 Volts a typo ?

no typo, my battery is dead, and everytime i use the battery it gets worse and worse, my test station is dieing on me:(

i did not get to test this with a hot battery:(

The light is Bright!

[hartiberlin]

Well, we need to see a scopeshot of theoutput waveform.
cause at 36.6Volts the bulb should not be this bright...
Probably it still has spikes in it, which the multimeter
does not register.

At which frequency do you drive this circuit ?

By the way, you should never discharge a lead acid accumulator
below 12.0 Volts, otherwise it is dying.
So never discharge it fully into the deep low voltage to still have a healthy
battery and recharge it, when it crosses the 12.0 Volt marking in open cell voltage,
cause it is then already 80 % discharged.(when I remember correctly)

[hartiberlin]

volts across the battery is 11.76 volts when the ac light is on, the amps draw from the battery is 2.11 amps


the output is 36.6 volts DC UNDER LIGHT LOAD and 200v DC under no load

the amp pulled by the light is .27DC

So you are pulling out of the battery about 25Watts,
but at the bulb only having 10 Watts ?

Looked much brighter the bulb than 10 Watts to me.

You need to measure this thing with a scope.

Can you loan a scope from a friend or visit a friend
who has one with your circuit and try again ?

Many thanks.

i have a old scope here that has been repaired, the only thing you will see from the scope is the waveform, would you like that?? and it is a 5mhz scope i was told.
