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 – 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
