Abstract :
The paper discusses design and development problems of auxiliary power supplies (APS) with output powers up to 100 kW to be used in 3.0 kV DC commuter trains. Focus is on the implementation of 6.5 kV IGBTs in IHVM of APS. Using single 6.5 kV IGBT module instead of several series-connected IGBTs or even converters helps to achieve more reliable, efficient, compact and lightweight design than ever. For the APS with output power up to 100 kW, the simple half-bridge topology and two 200 A 6.5 kV IGBTs (one for the TOP and one for the BOT switch) it is sufficient to fulfill all the design requirements. Given paper generally deals with topology selection, analysis of switch losses and cooling of HV IGBT as well as with control and protection of the new power supply. Some generalizations and practical considerations are given.
