This paper presents a high performance 12 kW motor drive system for an aerospace application. In order to achieve higher power density and reliability, the system uses a PMSM motor, SiC MOSFET inverter, high performance PWM control, and liquid cooling with phase change material. A power density of 33 KW/KG was achieved for the power inverter and control electronics excluding the cooling loop, and...
The power converter for more electric engine in aircraft requires high power density, which makes SiC extremely attractive for this application. In this work, a 50 kW SiC high power density converter with the topology of three-phase two-level voltage source inverter is developed. Meanwhile, an accurate mathematical model for the power loss and efficiency calculation is proposed, which is based on...
This paper deals with the performance assessment of different permanent magnet motor drives topologies for Starter/Generator in More Electric Aircraft systems. The comparison is focused on the power electronics part of the system, assuming the possibility to adapt the machine structure to better fit the specific configuration. Simulations performed with Matlab/Simulink and Plexim Plecs will be used...
This paper deals with the performance assessment of different permanent magnet motor drives topologies for Starter/Generator systems in aircraft applications. The comparison focuses on power electronics topologies, evaluating, by means of simulations performed with Matlab/Simulink and Plexim Plecs, some relevant key points such as efficiency, losses and motor current harmonic distortion. For all the...
