Question

The transformer between diodes confuse me,I don't know how to work this problem

Given: Use the CVD7 model for the diodes. The AC line is 208 VRMS @ 400Hz. The line voltage is reduced by the transformer according to the transformer ratio 50:1. R = 75 Ohm, C = 2200 micro F. Find: Find the average DC output voltage, VoAVE, and the pcak-to-pcak ripple voltage, Vr. What values of VPIV | and IDMAX| does each diode have to tolerate? Sketch and annotate 2~3 periods of the waveforms of the output voltage, vo(t), and the current through D3, |iD3 (t)|. Hint: On part a), Do not use the exact integral definition of VoAVE, instead use the approximation: VoAVE VoPEAK -1/2 Vr.
