摘要

In order to suppress the harmonics in the Integrated Electrical Propulsion System (IEPS), a power transformer with harmonic suppression function, called Harmonic Shielding Transformer (HST), is proposed in this paper. The HST is a three-winding transformer, and three windings of the HST connect to power source, service utilities and filters respectively. The operating principle of the HST is analyzed, and the calculation and improvement of harmonic suppression effectiveness are presented. The HST can prevent 70% of total harmonics of power source from injecting into service utilities through power transformer if the parameters of the HST are reasonably set. The validity of theoretical analysis is verified by experiment.
