Any expert know how to solve this rectifier problems? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Currently doing a rectifier practice exercises. But, I have two problems in doing it.

Can experts here give me some guides please?

The diagram 1 and 2 show the 1-phase Half wave and Full wave bridge rectifier configurations respectively.

See the two attachment files.

Assume that the diodes are perfect diodes i.e. the diode
on-state voltage drop is negligible.

My two problems,

I want to plot the Vp, Vs, VR and IR from 0 to 20ms and calculate the de voltage across the resistor R. Can experts here guide me?

Really hoping experts here could give me some guides about this two problems.
Thax you.

The frequency used in your schematics specifies 50 Hz, so the plot period of 0 - 20ms will equal 1 complete cycle. I would assume it is a sine wave and plot 5 points, 0, 5, 10, 15 and 20 ms. Your transformer ratios will give you the secondary voltage for your calculation, and Ohms law will sort out Ir.
Also RMS = .707 of PP, but I sure you already know this
