[EE Faculty Colloquium] Overview of Research on Pulse Width Modulation, Motor Control and Electrical Machines

September 29, 2023 @ 4:00 PM - 5:30 PM IST

Title: Overview of Research on Pulse Width Modulation, Motor Control and Electrical Machines at EE, IISc

Speaker: Prof. G. Narayanan, Professor, Electrical Engineering, IISc

Venue: MMCR, EE & Online Teams link

Time: 4pm, 29 September 2023

The talk will provide a brief overview of research on pulse width modulation (PWM), motor control and electrical machines, which the speaker has been a part of, in the department of electrical engineering over the past 2-3 decades. Research highlights will be presented on the following aspects:

  • Space vector based PWM for motor drives and four-quadrant voltage-source converters
  • Offline optimized PWM for induction motor drives
  • High power converters for motor drives and active front-end converters
  • Power-electronic control of induction motor and its variants
  • Effect of inverter dead-time and its compensation
  • Induction motor drive-based emulation of wind turbine
  • Power electronic based emulation of electrical machines

Recent and on-going activities on the following with be discussed briefly:

  • Permanent-magnet-free high-performance motors based on reluctance principle
  • High-speed switched reluctance motors and contact-free electromagnetic bearings
  • Multi-disciplinary initiatives involving multiple departments, multiple institutions / organizations across technical domains

Speaker’s Bio:
G. Narayanan received his BE from College of Engineering Guindy, Anna University, Chennai, in 1992; MTech from IIT Kharagpur in 1994; and PhD from IISc in 2000. He has been on the faculty of EE, IISc, since August 2003. He researches in the areas of power electronics, motor drives and electrical machines. He has taught / has been teaching multiple courses in these broad domains.
