Why all the failures to natural disasters?

That is really split minded. You don't like putting up with all the blather and rude crude language, but get fascinated by the troll just the same. You are doing just what the troll wants. Hope you like being manipulated.

Oops. Got thinking about BIG engines. Not really portable. I wonder just how much power large Diesel electric train engines develop. Must be websearch time. Seems to be about 6000 hp (4.5 MW) tops and about 2500-3000 hp (1.9 - 2.2 MW) typical.

50 (or less) percent overpower (in kW) for the engine seems pretty common for emergency generator sets.

Now that i think about it, maybe more like many MW. Or maybe not. Emergency cooling of a 100 MW reactor may well take a lot of water per minute. If idle power is 7 percent of full power that is a continuing 7 MW to get out of the (100 MW) reactor. The Fukushima reactor units are more that 100 MW each aren't they?

Retarded bastards like you calling folks troll is a manipulation of the group.

You are about as much of a fucktard as an adult aged asshole can get.

___________________________ Car engine. Very portable. Build a car around it, take it where you need it, remove it from the car. A V8 Hemi can pump out 150 hp (or 200 hp for that matter) as long as you like.

May be the California side of the Nevada border. In an emergency, we can shut down I-15 and ship everything on I-40. As long as the nuclear waste stay within the state, Congress and Fed can't do anything against it. There are more people (votes) on the west than the east of the state.

Looks like China has some around 12,800 hp and some others down to 6k, but I think your 3000 number is what's normally run. It's probably more practical to run multiple units if more power is needed.

This is a discussion group. The subject is electronic design. You wouldn't understand.

"Pueblo Dancer" should sure qualify.

Crud, it's only a newsgroup. It ain't life.

John

Looks OK. Have you tried it in real life?

The transistor Iq depends on the opamp Iq, which can be tricky if you want to run class AB and avoid crossover distortion.

There are lots of variations on this circuit. I like to use fets instead of bioplars here, and usually cascode from the opamp rails up to the output transistors. And in extreme cases, replace the tansistors with active high-ratio mirrors.

The remarkable thing about this circuit is its essentially perfect current splitting.

If only you could remember that consistently.

"Does you or your"? DimBulb, you're outdoing even yourself!

An equivalent circuit formed my headphone amplifier in the first stereo i built in my teens. Different parts and bias values.

This sim is cool because it shows opamp power lead currents matching the output current. I don't believe it shows opamp idle (bias) current though.

Absoloutely. I had some fun verifying stability.

Given the usually so-so actual PSRR of real opamps i would use bipolars for the "cascode".
