Akula0083 30 Watt Self Running Generator.

So the actual schematic still hasnt the ground connection on the other side of the voltagedivider and the LED? Seems strange to me. Anyone tested if its working this way? Cant imagine that unless pin 16 of TL494 is able to provide a ground somehow... Or am i totally wrong? Maybe one of  the pros here like verpies or TK can have a look at this and give a statement?

Hello From other Planet:

Yes, you are correct, Pin 16 is the Error Amp +in :   It does NOT provide ground it is an input for error amp calculation.

Please see my post #83 ; http://www.overunity.com/14378/akula0083-30-watt-self-running-generator/75/#.UyJU1T9dX7c

The attached photo is of a H-bridge GDT circuit I built to drive the primary of a Tesla Coil.
Yes, it is Common Emitter configuration like the Schematic with the Ground lead to both Pin #16 and the voltage divider.

Wish I knew more about the other schematic that does not have the Ground lead-- guess I would have to build it to see what the deal is, but my first instinct says that you are correct and that the Ground Lead IS necessary in that configuration.

take care, peace

EDIT the photo should say TL494CN not TL4949CN

Guys,

Can a $2 chepo chinese digital mutimeter set its knob at 20 V DC, charge a lead acid battery converted to lead alum battery, from 9.20 volts to 9.87 volts in 15 minutes. 

When I am writing this post, the voltage is increasing further.

I am confused, whats happening.

Best,

I am a little confused now..  I might be thinking of a different ground than what you're talking about.  I can't see the schematics with my phone.  Anyway it a good idea to see both schematics.

Best,

It 10.23 now, and increasing. Picture enclosed.
