Cheap DIY High Power/Voltage AWG Buffer Amp

<< < (3/3)

Interesting I have pdcl2 for via copper plating. After a lot of failures with echem I never bothered to try the dubious process in favor of a eyelet staking kit. I have seen weird phenomena with ball lightning before so I find cons fusion interesting. I don’t have heavy water though

Recall Pons and Fleischmann seem to have made similar errors!!

Best advice wrt the LM3866 is get one and try it out, it's cheap enough!!

Yes simply multiplying AC voltage and current, whether rms or not,  doesn't always convey the correct answer. This is because the "assumption" is the voltage (or current) is dissipating into a resistive load. What really matters is the apparent Power Angle, or Real Power and Imaginary Power, where the Real Power does work and the Imaginary doesn't. This is a serious problem with the Power Grid as the Reactive Power (Imaginary) causes losses in generation and distribution but doesn't do work (Real) at the loads. Much effort goes in to correcting the Grid Power Factor (Power angle close to zero) which relates to the quality of the Power involved.

Anyway, search here as we may have designed an AWG Power Amp around the LM3866 and created & procured a PCB for such, although don't recall ever assembling one.

Also, vaguely remember way back a massive meltdown in one the labs involved with researching Cold Fusion here in US and another in USSR. So be careful!!

Keep us posted on your progress!!

Best,

We did design a version of the High Current AWG Buffer Amp based upon the LM3866.
