Development and Implementation of a 1.5 MW Inverter and Active Power Filter System for the Injection of Regenerated Energy in a Spoornet Traction Subs






Development and Implementation of a 1.5 MW Inverter and Active Power Filter System for the Injection of Regenerated Energy in a Spoornet Traction Substation

Autor: Fuchs, Heinrich Daniel
Resumo: Spoornet is one of South-Africa’s largest railway companies. It is very important to operate the railway system as cost effectively as possible. A large portion of the railway operates from 3 kV DC traction supplies. One method of cost saving is to utilise the regenerative braking mechanism of the electric trains.

IGBTs at Higher Operation Temperature








www.bodospower.com September 2011
IGBTs at Higher Operation Temperature Impact on inverter design
The development of IGBT power modules has always been characterized by the
continuous increase of the power density for cost reduction and design optimization
of the complete frequency converter system [1]. The requirement of higher power density
is directly associated with increased current per chip area and therefore an increase of
the junction temperature during the operation is expected.
