A little help please i am building a 10 meter linear amplifier that needs a 13.8 volt 80 amp input I also need to build a power supply to handle it so i feel it needs at least a 13.8 v 100amp power supply to operate it effectively!! Does any one have a link to plans or plans them selves that i can use. I have a old (vintage power supply (tube type)) for some hv ac output although i havenot checked the output of this unit the outputs come out of the unit as a tube type connectors 11 pin or 16 pin. It maybe a good start!

 

10 meter amplifier?

what does that mean?

 

10 meter wavelength. Radio amplifier. CB Whats your 10-9 goofydad?

100AMPS? You are a goofy dad.

What are you transmitting, and have you considered other options?

I guess you want a huge range.

here is an option

Get a truck or golf cart 12v battery, a 130 Ampere GM alternator, and a 2-1/2 HP electric motor. Spin the alternator using the electric motor and a V-belt drive. You'll need to spin the alternator at between 6,000 to 9,000 RPM to get decent power out of it while keeping the air pumping through it to keep it cool.

Power the motor using 240V.

holy electronics maniac batman

 

If you're willing to throw a little money at the problem, see if you can parallel two of these.

 

If he's going to spend that much, might as well get a quality unit, like this one:

I like Lambda supplies. Not cheap, but not likely to break, either.

You can adjust the output voltage anywhere between 10.4v and 14v inclusive.

1% regulation at 100A output is pretty darn good, I'd say. Power factor is .99, 88% efficiency at full load.

Trying to build a supply like that at home would be a major engineering effort. You'd probably wind up spending 3x that much and the resulting supply would not be nearly as efficient or reliable.
