D 4.71 It is required to design a full-wave rectifier circuit using the circuit of Fig. 4.22(a) to provide:
(a) an average output voltage of 10 V
(b) an average output voltage of 25 V
(c) a peak output voltage of 20 V
In each case find the required turns ratio of the transformer. Assume that a conducting diode has a voltage drop of 0.7 V. The ac line voltage is 120 V rms.
(a) 10.1:1; (b) 4.2:1; (c) 8.2
