2. Abstract
• Silicon carbide (SiC) based power switching devices have been extensively studied by researchers
and engineers in recent years because of their superior physical properties compared to silicon.
• However, the benefits of using SiC devices have yet to be fully explored, especially for highspeed
or high-fundamental frequency motor drive applications.
• Hence, this paper contributes to the understanding of the benefits of SiC inverters as applied to
high-speed or high-fundamental frequency drives.
• This research investigates the high switching frequency capabilities of SiC inverter to improve the
performance of high-speed machines or high fundamental frequency operation and achieve
lower weight and volume of the both motor and inverter

4. Existing System
• High-speed electric machine systems have been used widely in the industry recently due to
advantages such as high power density and relatively small weight and volume.
• There is an increasing interest in designing high-speed machines with larger number of poles to
further achieve the reduction of weight and volume.
• The fundamental frequency required by these machines can be multiples of kilo-Hertz. Silicon (Si)
IGBT technology has a major limitation to achieve these high fundamental frequency generations
in kHz range because of maximum switching frequency limitations.

5. Proposed System
• Due to the low loss characteristics, SiC based inverters can operate with much higher efficiency
than similarly sized Si inverter if the switching frequency and power rating are the same.
• The increased efficiency gain will translate into energy savings and weight reduction. Many
researchers have looked into the higher efficiency aspect, but they typically focused on low speed
machines.
• In reference, a SiC JFET-based integrated six-pack power module is characterized.
