Electronics Basics #04 | Full-Wave Rectifier: Bridge + Center-Tapped, V_DC = 0.636 V_m
PN DiodeInstructor: Dr. Süleyman Burak ÇELİK
Full-wave rectification explained step by step: bridge topology, center-tapped transformer topology, and the DC value V_DC = 0.636 V_m. What we cover: - Why full-wave rectification gives twice the DC value of half-wave rectification - Bridge rectifier operation with four diodes in a diamond - Positive and negative half-cycle current paths through the load - Average output: V_DC = 2 V_m / pi = 0.636 V_m - Silicon bridge loss: two diode drops, so 2 x 0.7 = 1.4 V - Worked example for V_m = 10 V: ideal 6.36 V, silicon bridge about 5.47 V - Center-tapped transformer rectifier: two diodes, one diode drop per half cycle - Practical trade-off: bridge is cheaper and common; center-tapped saves diode drop but needs a special transformer Builds on lesson #03, where we covered the half-wave rectifier. Next we move toward smoothing capacitors and ripple voltage. AcEdumy.com
