摘要

In railway applications possible interaction between power train and signalling system requires efforts to Electro Magnetic Compatibility (EMC) problems. With the progress of power device technology in recent years, it has become feasible to improve performances of power electronics systems; however EMI noise, caused by fast switching commutations in power converters, has to be managed. EMC control has, therefore, become a worldwide topic, and requests for EMI noise reduction have become very strong. In the paper, after a deep analysis of EMC features in railway applications, two innovative driving strategies have been introduced and characterized, in order to find a good trade-off between high power IGBT performances and EMI reduction constraints. Characterization and discussion are based on experimental basis.
