Smart converters implemented into auxiliary converter of public transport vehicles

This paper describes smart converters and presents results from real industrial application. The auxiliary converters in public transport vehicles are very important part of vehicles. The auxiliary converters consist from three-phase, inverters, single-phase inverters, chargers, power supplies of several different voltages. Nowadays converters contain powerful digital signal processors (DSP) with a lot of peripheries. High performance of the DSP predisposes new converters for complex systems. Working principle of converters is often very similar. Based on the similarity of converters were designed and created universal, adjustable control programs for each group of converters. The creation of universal adjustable control programs allowed to design and create smart converters. The smart converters are adjusted automatically. When the smart converters are connected to the auxiliary converters, they are adjusted automatically. The converters accept correct settings without external support (service staff). After that the converters are ready for work. The implementation of the smart converter improves reliability and reparability. Repair time is shorter. Requirements on staff are low.
