hello , guys . i'm a new member in this website ,, i built a bridge rectifier circuit and i found the situable values for each component ,, and the only thing i need now to get it done is the calculation part including the formulas and i need to know what the calculation should i consider ,,thank you guys ,, hope to hear from u sooooon

 

Calculation of what? In the real world, a bridge rectifier produces a positive and a negative voltage. To filter the ripple, a pair of capacitors are used. Capacitors are cheap, so choose a voltage spec close to double the voltage out, and a capacity mostly limited by space. If 100 uF is enough, use 470. Probably not $.30 difference.

 

first of all thank you for your reply ,,,i made up the rectifier from :
v=10 volts
four diodes = 1N1206C
capacitor=100muF
RL=100m ohm
but it still doesn't work,,,,
one more thing i need the formulas to calculate the output DC voltage across the load resistor.

 

Could you show the schematic. We are all familar with how they should be wired, but we don't have a clue how you did it.

 

Your using a 100 milliohm resistor?

 

1N1206's are pretty heavy diodes. Stud mount and good for 600 vots @ 12 amp. You only have one filter capacitor. 100 microfarad is way too small for any significant current - 10,000 microfarad might be more like it (assuming you are going to pull something like the 12 amp rating).

Then you say it doesn't work. Did you mount the diodes all to the same piece of metal? That would short all four together. I can find specs on 1N1206N &-R types, meaning standard and reverse polarity, but no mention of -C types.

We are going to need a schematic to tell what is going on.

 

Standard rectifier diodes have a fairly large forward voltage drop across themselves (0.7v-1.2v depending on load) when compared to Schottky rectifiers (0.32-1v depending upon load)

This isn't as much of a concern when rectifying high voltage as it is with low voltage.

You will still need to size your rectifiers for your expected load current.

International Rectifier's website has a great deal of information on selecting rectifiers.

 

 

engineers,,, this is an image of the bridge rectifier that i have told please check the values of the components,,,,,,,,is there any formula relates the AC input with DC output,,thank you

 

yes ,, i do

 

i have the schematic as .gif ,,,, could anyone tell me how i can upload it?

 

i have the schematic as . gif,, could anyone tell me hot to upload it?

 

Go to advanced mode and follow the directions for uploading the image file.

 

well,, it asks for the URL of the image ,,, could u please tell me how i could insert this URL at the time i have the Image saved in the hardesk,,thank you

 

you haven't uploaded the diagram yet.

We can not access your E: drive from the internet

 

You use the Browse function to direct the uploader to the file on your HD.

 

i'm afraid, there is no browse button in the form,,, well,,, would u mind sending it to your E-mails ?

 

There is no point in clogging up folks e-mail with pictures the rest of us won't see.

1) click on the paper clip (a widely used symbol for "attachemnt") next to the "A"

2) in the window which opens, click "browse"
