k.Auxiliary SiC Inverter Module

Silicon carbide technology for auxiliary converters

 

Kiepe Electric Function Module Concept (FMC)

Whether it’s for the lighting or the loudspeaker system, the coffee machine in the on-board restaurant or the power sockets at the passenger seats, the passenger information system or the air conditioning: Kiepe auxiliary converters provide power on railway trains, underground and suburban trains or busses and are designed to operate with all standard UIC catenary supply voltages.

Kiepe Electric patented isolating transformer topology achieves very high efficiency rates of more than 95 percent. Designed to produce as little power loss as possible, Kiepe auxiliary converters are natural air convection cooled. Kiepe Electric auxiliary power converters have an MTBF rate of >50,000 h and are designed to remain maintenance-free for 20 years or more.

Kiepe auxiliary power converters are structured with standardised modules and are individually scalable (Function Module Concept - FMC). Depending on the technical requirements, e.g.: the input voltage(s), output power(s), number and type of energy consumers, etc. – Kiepe auxiliary converter FMC-modules are engineered and customized to fullfi ll the most demanding form, fi t and function requirements.
