The objective of this paper is to analyze a novel high-speed integrated motor-compressor drive system and investigate the opportunities by using gallium nitride (GaN)-based inverters. The proposed integrated motor-compressor is a combination of electric machine and axial-flow compressor by shaping the rotor pole of the electric machine into airfoils. Hence, the proposed integrated motor-compressor...
The purpose of this paper is to investigate high-speed machine design enabled through the use of silicon-carbide based power electronic inverters. Silicon carbide based switching devices have superior properties compared to silicon based devices, and they are able to change the paradigm for high-speed machine design. High-speed machines with a higher number of poles are shown to reduce the machine...
Rapid advancement of gallium nitride (GaN) based device technologies enables the possibility to design inverters that have superior performance capabilities compared to Si-based inverters. It is prevalently acknowledged that GaN-based switching devices outperform the Si-based counterparts in many aspects such as lower power consumption, and faster switching frequencies. GaN devices will benefit many...
