Birth Of The Gigawatt

MEXICOWANDERER

Jim in Denver's Megawatt has been perverted. Larger toroid choke, 80 amp 150 volt diodes rather than 30 amp 100 volt. Panasonic 680uf caps, 10x more airflow via two external roof fans. And...

57.2 amperes* into 12.0 volts for 9 hours and 10 more or less minutes. 16.67 wide open volts. Didn't even breathe hard. Cool to touch on rectifiers and bi-polar transistors. Like having a Derringer 12-gauge.

I did delta the three positive and three negative circuit board terminal strip output screws. Total fans drive current .84 amps. Transistor life will be a "maybe".

Sounds an impressive project to take on.

Toroidal Transformer does have qualities that is better than regular generic rectangular shaped core.
Not only that it is more efficient on a given size, it possesses better magnetic leak shielding, thus, minimizing hum in sensitive audio/video equipment.

Yes, EMF shows lines on my TV. . . and with all these complexities of new electronics, these lines even show up on my forehead and even more increasing as days go by.

One blaring disadvantage over conventional (rectangular core) transformer is cost. Hence, toroidal converters cost more than conventional model. Frankly, I don't think they make this rectangular core for RV any more. They are too heavy.

Since the coil has to be wound around doughnut shaped laminates, production is slow compared to rectangular laminates.

You did mention gigawatt. What exactly is the projected output in watts?

Interesting project indeed. . . care to share the result?

Is it a variable output and is it regulated?
