Power electronics methods to improve energy efficiency in the public transportation system

Abstract

The energy, electrical and thermal assessments are complex audit procedures that are currently regulated by prescriptions, technical rules and international and national guidelines. Such procedures are applied in order to evaluate the energy efficiency of the material and human resource allocations within any enterprise. This paper presents the technical aspects encountered throughout the elaboration of the energy audit for an urban electric transport operator. Methods taken to optimize the working states of the integrated power components and their efficiency are also presented.
