Step 1 of 3 4.001E Refer to Figure 4.3 (a) for a rectifier circuit in the text book. Refer to Figure 4.3 (b) for an input wave form in the text book. Case (i): During the positive half cycle the diode is in forward bias condition. The positive v, causes the current flows through the diode in the forward direction. In forward bias condition the ideal diode acts as a short circuit. So, the output voltage is same as the input voltage. The equivalent circuit is shown in Figure 1. + = 0 - + + v₁ R Figure 1 Step 2 of 3 Case (ii): During the negative half cycle the diode is in reverse bias condition. In reverse bias condition, the ideal diode acts as an open circuit and the current flows through the diode is zero. Hence, the output voltage is equals to zero. The equivalent circuit is shown in Figure 2. + - = 0 + + v₁ R 0 Figure 2 Step 3 of 3 Hence, the final conclusion is, When That means during the positive half cycle, the diode is on and the output voltage is same as the input voltage. When v, = 0 V That means during the negative half cycle, the diode is cut-off and the output voltage is equals to zero. Draw the transfer characteristic curve versus 1 1 v₁ 0 Figure 3 Thus, the transfer characteristic curve versus is shown in Figure 3.
