Course Abstract

1. Digital controllers find applications in power electronics, industrial drives, automotive, motor control, etc. This course has been designed with both theory and lab sessions. The course focus on modeling, design and control schemes for power electronics interfaces like DC-DC converters, DC-AC inverters and AC-DC PWM controlled rectifiers for EV and renewable applications.
2. An overview of F28379D, peripheral programming features and examples specific to power applications will be introduced in this course. Few sessions are organized by Texas Instruments and MathWorks to give a brief overview on the DSP.
3. The lab sessions are organized such that participants can learn the concept of real time modelling of the DC/AC power electronic systems in DSP and implementing the control schemes. This course will be helpful for students pursuing a career in Electrical and Electronics Engineering.

Outcome of Theory/Lab Sessions:

1. Participants will have an understanding of programming for various modules like GPIO, Timer, ePWM, DAC/ADC which are essential for power applications and digital control implementation in  system development.
2. Participants shall get a theoretical understanding of modelling aspects of power converters including  PWM controlled DC-DC, DC-AC and AC DC converters.
3. The concept of Real time modelling and closed loop controller design and its implementation in DSP for the PWM controlled DC-DC, DC-AC and AC-DC converters.
