🔍 Key Concepts

• Follow the power flow in the diagram: from exciter field → exciter armature → 3‑phase bridge rectifier → main field. • Remember what a diode bridge / rectifier does in basic electronics (AC vs DC). • Note that the main armature / stator windings are where the generator’s AC output comes from, not the field windings.

💭 Think About

• In the illustration, is the exciter armature drawn as an AC or DC winding, and what type of current normally comes out of an armature like that? • What type of current must flow in the main field windings of a synchronous generator to create a steady rotating magnetic field? • If a 3‑phase bridge rectifier is placed between a 3‑phase winding and a DC field winding, what conversion is it performing?

✅ Before You Answer

• Verify which two components are directly connected on each side of the 3‑Ph Diode Bridge in the illustration (input vs output). • Confirm whether a rectifier ever converts DC to AC (think about its normal one‑way conduction behavior). • Be sure you are not confusing the main armature (stator), which supplies ship’s AC power, with the main field (rotor), which needs DC excitation.
