Railway Auxiliary Power Supply System: A Modular Multilevel Converter Approach

Transportation Research Procedia, 2023
When it comes to power railway systems, two main aspects must be considered: (i) the power of the propulsion of the train, which is responsible for the movement of the train; (ii) the power of the auxiliary services, which is responsible for the power inside the train for commodity and service of the passengers.

Applications of an Auxiliary Resonant Commutated Pole Converter [PDF]

APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
The Auxiliary Resonant Commutated Pole Converter (ARCP) utilizes an auxiliary resonance circuit to enable zero voltage turn on in the main circuit and maintain zero current turn off in the auxiliary circuit. The ARCP converter can therefore be designed with snubbers that are undersized for the power rating of the switches. Another advantage of the ARCP
