Hello

I'm using a dc motor with high torque..
I'm using a power supply gives 2A output and that is enough without load ,but I need a power supply circuit with higher current for high loads..

would you please help me..
thanks in advance...

I don't know where you live, so I don't know if there are any Radio Shack stores in your geographical area.

But in the even that there are Radio Shack stores near you, they offer a 13.8, 10 Ampere power supply for about $75.00US.

The alternative it to purchase the component pieces and build one. You will need a step-down power transformer that will take the "Line Voltage" in your area and reduce it to about 9 Volts AC ---> 9AC * 1.414 - 12.726VDC. From there, you'll need a 10 to 15 Ampere bridge rectifier and some capacitors rated at about 10,000uF to 20,000uF with a 35 to 50 VDC voltage rating.

If you do this, make sure that you provide for current overload protection for the power supply input and outputs. Also, make sure that you provide an output fuse that will be high enough to deliver adequate current to the load, and at the same time protect the power supply from excessive current drain, as this much uncontrolled power could be a safety hazard, starting a fire.

You can avoid reality, for a while.  But you can't avoid the consequences of reality! - C.W. Livingston
