hv power supply

hv power supply question if you have a 2300vac at 3.5 amp's ccs transformer and wanted 4600vas at 3.5 amp's can you use a voltage doubler or will it change the amp's available and what would the voltage be with a doubler I think with a full wave bridge its volt's x 1.4

 

[Captain Kilowatt]

2300 vac will give you about 3250 Vdc with a full wave rectifier.A voltage doubler will give you twice that,around 6500 Vdc and will have poorer regulation.

and less current available to use. All things being constant, anytime you increase available voltage you decrease available current.

so qrn it would be better to use a transformer with a higher voltage I have a peter w Dahl transformer with 2350vac 3.5amp's ccs but I need 3800-4000 vac 2 amps ccs to get close to 5000vdc under a lode should have paid closer attention to grand pa i think that's about what he said about a doubler circuit he was a greet amp builder I stayed in his shop all day win I could to help just cant remember doing a doubler with him thanks qrn 4 the help

Best regulation is obtained with a full wave rectifier.Just remember that the DC volts is equal to the AC voltage times 1.415 (the square root of two).The volts may sag a bit under load but it will sag even more with a voltage doubler,like twice as much.

just give peter dahl an email tell him what your requirements are and your set for a good wait not to mention the price hike

same thing going on here with building the modified sb-220 up to the 5tubers just getting a fixed price on a transformer is hard sure hate to quote a price to a customer then it be over that when it shows up

Texas mud duck I have a brand new peter w dahl Trans p/n sb-220-x2 1175vac 3.5amp ccs for 6 z tubes or maybe for 4 3cx800, 4cx800 or something that needs 3.5amps continues it was made for a high amp replacement Trans for the sb220 has the same primary taps and voltage as the stock one just a lot more amps fore 6 tubes it ways 70 ponds it needs a good home for sale or will trade for 3800-4300vas transformer
