Step 1 of 10 4.020E (a) textbook for wave with model with Neglect effect equivalent upper center tap R Figure voltage expression Consider the wave rectifier diode conducts both waveform together V. Figure 2 Step 3 of 10 waveform Figure 2 the input reaches VD diode starts conducting The diode terminates and hence the total conduction Therefore that Hence 2sin tero-crossin points Step 4 of 10 The average value Observe from the the time limits and Calculate the output Here, interval and Therefore then -1 and Therefore Thus, (c) peak current occurs the peak + + D R 01 Figure Apply Kirchhoff's voltage the diode current is Determine percentage cycle during which The total duration the one complete The duration for which diode =[x-20]+[x-20] The fraction cycle during which %Tc The expression for %Tc Step 7 of 10 Consider input 12V Find the Substitute 0 16.97 %Tc 100 (since, =97.4% Thus raction cycle 97.4% Determine average value Recall th expression the average value and in the expression for Therefore average value VD Step 9 of 10 Calculate the peak diode current expression and 6.97 16.97-0.7 100 =0.1627 Thus, 163 mA Step 10 of 10 Determine peak inverse voltage PIV The peak inverse voltage full-wave and 16.97 PIV =33.94-0.7 =33.24 Therefore 33.24 V
