    摘要: Each arm forming a three-phase full wave rectifier bridge includes a semiconductor diode, a current transformer and a fuse. The current transformer is connected to a pulse extinction indicator circuit through a pulse transformer. When no current flows through the arm for a predetermined time or more, the pulse extinction detection circuit produces a DC signal indicating the blowing of the fuse. The rectifier bridge, the current transformers, the fuses and the pulse extinction detection circuit are all disposed on the rotor of a brushless synchronous machine.
