Thanks for the reply. If the Load is 10ohms, what will be the current on the resistor? When using an ammeter in simulation, I am getting 338mA.Are you looking to calculate Absolute Maximum Ratings, or are you more interested in typical ratings?
I'm not sure which ratings you think are calculated as opposed to measured.
In any case you want to have an adjustable AC source and an adjustable load. Then you want to have two more meters connected as ammeters.
Now you can construct a set of characteristic curves describing the voltage and current as you vary either the AC source, or the load. It is tedious, but instructive work.
For example:
Plot the data.
- Set the RMS AC source voltage at 30VAC
- Set the load at 60Ω
- Measure the RMS AC current
- Measure the Peak AC voltage across the load
- Measure the Peak AC current across the load
- Change the the load
- Go back to step 3, n times
From this data you should be able to tell the forward voltage drop of the diodes at various current levels.
With a scope you might be able to see the reverse recovery time.
One time only you might be able to find the maximum reverse blocking voltage
You get the idea.
