Overview:
There are two popular and often times competing high-voltage power devices available to designers. These are the high-voltage power MOSFET and IGBT. Each device has its strengths and shortcomings, which are very application and operating condition dependent. Specifically, the application area of a motor inverter often needs careful consideration regarding the power device to be selected. This is where subtleties such as the recovery performance of the reverse diode often play a key role. The intent of this webinar is to help provide some insights into these devices and help guide designers to a suitable power device for their given motor inverter design.

What attendees will learn:

  • An understanding of the differences between a high-voltage MOSFET and IGBT from a device structure, operational principle, characteristics, and application perspectives.
  • How to estimate power device losses in a motor inverter application.
  • How best to select a power device for a small motor inverter application
    (100 W to 5 kW range)

Duration: 45 minutes + Q&A

Who should attend:
Engineers working on power supply and motor drive designs.

Prerequisites:
Interest in high-voltage power devices and the motor inverter application area.
