AV_m
B2V_m/π (≈ 0.637 V_m) — both half-cycles inverted to positive
CV_m/π
D0
Answer & Solution
Correct answer: B. 2V_m/π (≈ 0.637 V_m) — both half-cycles inverted to positive
**Bridge rectifier:** 4 diodes, both half-cycles
→ positive. V_avg = 2V_m/π.
**RMS:** V_m/√2. Ripple lower than half-wave (γ = 0.482).
With capacitor filter, ripple further reduced.
Most common power supply topology.
