How Can I Increase the Amperage Output of an AC to DC Converter?

AI Thread Summary
Increasing the amperage output of an AC to DC converter is generally limited by the ratings of key components, such as the transformer and rectifying diodes. Modifying existing equipment can lead to overheating and safety hazards, making it impractical for novices. Instead of attempting modifications, purchasing a more powerful, commercially available power supply is recommended. The output is constrained by the physical size of the transformer, and while lowering the voltage may yield slightly more current, it risks overheating. Overall, for higher power needs, investing in a larger transformer or a higher-rated power supply is the best solution.

hey guy I was wondering if there was any way to increase the amperage output of an ac to dc converter, it is a 120v ac input that outputs 13v dc at 3.42 A. is there any way to boost this output?

P.S. Ya'll are the best, This is by far one of my favorite places to be on the web. kudos on a job well done.

The current available from a power supply of this kind will normally be limited by the ratings of certain key components. Exceeding these ratings is likely to result in failure, which can cause overheating, fire and electric shock hazards.

Modifying mains powered equipment is not a job for novices. It would probably be uneconomic to make the modifications needed, so even someone who knows what to do in principle would most likely buy a manufactured product. If you need a more powerful supply, you would be far better advised to buy one.

Generally that current output (and therefore power output) is limited by the physical size of the transformer in the linear power supply. The only way to get more power out is to buy a bigger transformer. The bigger transformer model will also come with bigger rectifying diodes.

If it's a switching power supply, it takes a bigger transformer and bigger switching semiconductors.

So the short answer is no.

Nope... You get 13 * 3.42 = 44.46 watts from your wall-wart and that's it. You can probably get a bit more current if you can deal with the voltage being pulled lower than 13, but the poor thing will probably overheat eventually.
 
I don't know if size is a factor, but this site,

http://www.trcelectronics.com/12-volt-power-supplies-mid-chassis-1.shtml

was helpful when we needed a 12VDC supply with high current for a project. Since you want high power, it's hard to get too small in size, because, like everyone else said, the components are big at higher ratings.

Hope this helps.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
