🔍 Key Concepts

• Relationship between number of phases and pulses in a three‑phase full‑wave controlled rectifier bridge • How many SCRs (silicon controlled rectifiers) are used in the rectifier and inverter bridges in figure A • Difference between a basic 3‑phase bridge (figure A) and the more complex transformer/dual-bridge setup in figure B

💭 Think About

• Count how many SCR devices conduct in one complete electrical cycle and how many distinct DC output voltage steps (pulses) that produces from a 3‑phase source • Compare the simple single-bridge arrangement in figure A with the dual-bridge, 30° phase‑shifted arrangement in figure B—how does adding a second phase‑shifted bridge change pulse number? • Recall the standard rule: for a 3‑phase full‑wave bridge, pulses per cycle are related to the number of phases; how does that rule apply here?

✅ Before You Answer

• Verify how many rectifier bridges are used in figure A (one or more?) • Confirm that the AC supply in figure A is a single 3‑phase source without phase‑shifted transformer pairs feeding multiple bridges • Before choosing, match the figure A topology to standard names: 6‑pulse bridge vs 12‑pulse (dual bridge with phase shift) and select the pulse count that corresponds to a single 3‑phase bridge
