BORDLINE M: A very high-efficiency AC/DC/DC converter architecture for traction auxiliary services

摘要

The power needs on a train are manifold. The traction itself requires power, but so do many auxiliary consumers ranging from traction excitation, to on-board lighting, heating and air conditioning. Space and cost constraints are increasingly leading to demands for a single converter able to cover all these needs. Such a converter must supply both AC and DC outputs. Its output is required to meet high standards, it must nevertheless deal with a wide range and quality of input power conditions. ABB Review takes a look at some of the technologies behind the company's BORDLINE M series of converters and some of the challenges involved in its design.
