AG, Belfior,

frankly i have no idea what to expect here, signals sure look clean, and almost no spikes are seen like it should
according to V8Karlo.

No resonance involved also as far as i can see, just nice square wave signals between 10 and 100Khz.

We do transform from DC to AC (push pull) and via the feed back loop across C2 back as DC to the source.

I have 2W input and 650mW across B1, meaning we use 1.350W in the Controller/Push Pull section.


I do expect V8Karlo to comment now on how to improve on / correct this circuit so it matches his expectations.

Regards Itsu

Hi Itsu,
V8Karlo emphasises spike generation in his text, so I have an inkling that he may have a very poorly constructed circuit generating spiky waveforms and getting false readings on his multi-meter.

2 Watts total in, about 650mW across the 5W / 12V bulb, so dimly lit.

Hi Itsu. So approx. efficiency of your test setup is about:
0.65 / 2 x 100 = 32.5%
Now that is seriously poor performance.

Hoppy,

yes, that could be, therefor any input from him would be appreciated.


Void,

yeah, if you include the TL494 and IR2113 power, like it should.
Its also like you mentioned, with feedback the input goes up big time.

Hi i havent got what chip you're using but i just ran a test on a MC34063 switch mode device if I run it with no load I get

current drawn  5ma     freq 180hz, a pulse width of 10usec and period of 5.4msec
current drawn 150 ma freq 06khz,  a pulse width of 10usec and period of 10.5usec

So it really depends on your circuit your using and driving

Hi guys

Itsu thanks a lot for the update.
The low amount of current that returns back, is mostly due to the fact that the total voltage potential across Czero and L1 is lower than what V8Karlos thinks. Circuit presents a steady 12V across eacch one of them which is not true.

V8Karlos
Note1: In a similar way of thinking, a capacitor in series with the input voltage will also collect some potential which can be added in series with Czero and L1 (Look attached drawing). I have already tested that in an other device and i collect back the half of the consumed energy over a half of cycle. I'll post more on this later as i am at work right now.

Note2: Push pulls don't look quite the best choice for this teqhnique as it is beter for me to give some time for the energy to go back before we fire again.
