    There is an increasing demand for efficient high power/weight traction auxiliary power supplies for use on trolley buses, light rail, metros, locos and carriages worldwide. Typical power ratings vary from 1 kW to 100 kW with a wide variety of input and output voltage demands. These requirements necessitate that a flexible front end high frequency power processing technique is adopted. Generally, w... View full abstract»

    The BNU static power converter is used for the auxiliary power supply and battery charging in LRVs and other vehicles for public transport. It is conceived to replace the motor alternator set which was frequently used previously. It can also be installed in existing vehicles. The operating range of the converter comprises DC 600 V and DC 750 V lines without modifications. The static converters dev... View full abstract»

    The author describes the design of an auxiliary power supply for Dutch double decker train applications. Bus voltages of 500, 380 and 110 V are used. With the system of several bus voltages running through the train, the power converters can be located in relatively small spaces in the motorcars, and the equipment (inverters and compressors for airconditioning, cooling fans for the drive, etc.) ca...

    On rail passenger vehicles, a variety of electrical equipment is fitted to provide the appropriate level of facilities and comfort for the user. Static inverters are now the accepted means for deriving supplies compatible with the demands of these auxiliary loads. The modern auxiliary power converter has to satisfy the requirement for low cost, low weight, compact equipment with the conflicting de... View full abstract»

    Static converters for use in traction applications are commonly required to produce an AC output for driving air conditioning, blower and catering loads and a DC output for battery charging and other loads such as lighting and safety related circuitry. The converter outputs, both AC and DC, have typically been derived via an output transformer to provide galvanic isolation between converter input ... View full abstract»

    The auxiliary power supply system is one of the most crucial systems used in rolling stock. It provides power to every electrical system and equipment on a train including those that are critical to its safety and operability. A failure within the system would render the whole or part of the train nonoperational resulting in financial loss, operational problems to the railway and discomfort to pas... View full abstract»

    Prior to 1970, auxiliary power supplies on BR loco hauled coaches such as the Mk1 coach were produced by means of belt driven generators. In 1970, the Mk1 motor alternator (MA) set was introduced into service. This provided a much more stable supply and was a great step forward. Over the next ten years many improvements were made in performance culminating with the Mk12 MA set in 1980. When BR wer... View full abstract»
