A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ?t. The output dc voltage is Vdc and output rms voltage is Vrms . If firing angle is 180°, Vdc and Vrms respectively are
Options
A. 0 and 0
B.
C. 0 and - Vm
D.
Correct Answer
0 and 0
Explanation
Put a = 180° in Eqs
Otherwise also a = 180° means no conduction.
Hence zero output voltage.
