try to make a rectifier circuit to convert 14.5VAC to 14.5VDC

[5thcorps]

A wealth of information here and I'm excited to now be a part.
I have a small transformer model: DB41X26.5 120V AC TO 14.5V aC
Would like to add a rectifier circuit to it so I can use use it to power a dc project device. PLease, please, please forgive a guy like me who is somewhat new and trying to move forward into the more technical stuff other than just wires etc. Anyone have an idea for a rectifier circuit or is there anything they can be taken out of, like maybe a computer power supply

Hi.

General information about diode rectifiers can be found on Wikipedia.

And yes, you should find a rectifier inside any computer power supply. It could be four diodes or a device with 4 legs that contain the diodes.

Just don't devastate somebody's computer just for the sake of a rectifier

The transformer produces its rated 14.5V RMS only when it has its rated load. Its voltage will be higher when it has less than its rated load. for a small transformer the voltage might be double when it has no load or a light load.

The peak voltage of 14.5V RMS is 20.5V. If the DC current is1A or more then a full-wave-bridge rectifier (4 diodes) has a voltage drop of about 2V. Then a big filter capacitor will charge to 18.5VDC, not 14.5VDC. The 18.5VDC will be higher when the transformer does not have its rated load.
