Active neutral point clamped (ANPC) converter was developed in order to improve the performances of the neutral point clamped (NPC) converter in terms of the semiconductor loss distribution. Loss distribution depends primarily on modulation type used for generation of the switching signals, therefore it is important to find the appropriate modulation type that will allow the most uniform loss distribution...
New prototype of an auxiliary soft-switching power supply for the tram of the city of Zagreb was developed and built based on specifications of the existing auxiliary hard-switching power supply. A new soft-switching topology for the input DC-DC converter is proposed. It was possible to compare two power supplies built to the same specifications with only one basic difference: switching technology...
High performance control system, necessary to implement advanced concept for dominantly soft-switching based IGBT converter for traction applications, auxiliary power supply for light rail vehicles, is described with more detailed insight in some specific control solutions. Those control solutions, implemented by very compact hardware, based on DSP-FPGA digital core module, and its analogue module...
Electrothermal models of power semiconductor components are often too complex and requiring a long simulation time. Besides, there can be a situation that electrical and thermal behaviour of the circuit are not analyzed within the same department of a company. This necessitates an appropriate procedure of electrothermal simulation, sufficiently quick, accurate and simple, allowing an efficient exchange...
