WP2: Converter Topologies for High Speed Drives
Drives Topologies and Machine Losses Modelling for High
Frequency Drives
Project Plans & Objectives
 Utilise high switching frequency drives toward
improving in power density
 Identify optimal drives topologies
 Machine losses modelling to be used in conjunction
with PE modelling to evaluate drive efficiency and
performances at drive simulation level
 Machine and PE prototypes building in order to test
different topologies and validate simulations results
Work done so far – Drives Topologies

Work done so far – Machine Losses Modelling
Potential Outcomes & Exploitation Plans
 Identify novel drive topology to improve power density and
overall efficiency
 Machine losses modelling to be used directly in Simulink/Plecs
simulations without the need of FEM post analysis
 Evaluation of the efficiency of the complete drive topology (PE +
machine) with only one tool
 Evaluation of the effect of high switching frequency on machine
losses profile
 Dynamic switching frequency variation to seek for best overall
efficiency at different loads
