how can I multiply current 10 times without using a high power transformer?
I want to multiply current 10times for a second or two. So, is there any easy way to do that without using a high power transformer?
Thanx..!
Really what I need to do is, to increase the A/C current without using a transformer since it costs a lot..
The input is 230V & output is about 8 V, 30A.
Thanx a lot..!
*********************************************************************
Edit: If your output is 8V ac, then a transformer is unfortunately your best bet. You can get real fancy and do a switching power converter/inverter (sort of like the inverters that convert 12V dc in vehicles to 120V ac), but that solution is outside the ability of most designers. You would lose a lot of hair ... and if you're lucky, it MIGHT be cheaper.
*********************************************************************
I'm assuming you want to conserve power and increase I by a factor of 10 while decreasing V by a factor of 10? Remember;
P = V*I
A switching regulator will allow you to transform power from one form to another very efficiently (often 90% or better). It uses an inductor switched cleverly between the source and load. This is used in most modern power supplies instead of a transformer (like laptop supplies, cell phone chargers etc.)
Your question is a little vague ... you can increase current 10 times by reducing the load impedance (resistance) by a facto of 10. Ohms law V=I*R or I=V/R. Reduce R by 10, increase I by a factor of 10.
Hope this helps,
Dave
