Design and analysis of rotating diode rectifier for wound-rotor synchronous starter/generator

摘要

The structure of rotating diode rectifier were proposed in this paper to solve the excitation problem of brushless wound-rotor synchronous starter/generator. Rotating diode rectifier plays an important part of excitation system of main generator. Triple Rectifier was adopted to take the place of three-phase rectifier. The three phase armature windings connect to a full-bridge rectifier each other. Every full-bridge rectifier connects together in a series to provide field current for the Main Generator. Compared with three-phase rectifier, this new Rectifier can take advantage of all phase winding voltage at any moment, then the exaction fielding winding current of Main Generator will be increased. An experimental platform was built and experimental results verified the feasibility and advantages of the triple rectifier.
