| Abstract |
The launch of an integrated public transport system in large towns and surrounding areas (e.g. in Kraków and its conurbation) requires the railway network and tram network to be combined with a sufficient number of link points. The operation of such an integrated system will also require modern dual-system tramcars. As there is a difference in voltage between the two overhead supply systems, it is necessary to build a converter enabling tramcars to run on two different traction voltages, 3000VDC and 600VDC. This article sets out a proposed solution like that, based on a step-down multiphase converter. In addition, the article discusses the results of simulation testing, carried out on a laboratory model of a step-down multiphase converter that was designed and built to operate with a supply voltage of 300V, with a DC series motor designed for voltage of 48V/87A serving as load. |
