The Department of Electrical and Electronics Engineering (EEE), School of Engineering, Amrita Vishwa Vidyapeetham, Coimbatore, conducted a Workshop on Rapid Prototyping of Power Electronic Converters with STM Discovery Board on March 12, 2019.

Rapid Control Prototyping (RCP) is a process that lets engineers quickly test and iterate their control strategies. Consequently, mathematical models are automatically imported with MATLAB/Simulink (TM) on a real-time machine with real I/O interfaces to connect to real-world systems. RCP decreases development time by allowing corrections to be made early in the product process. By giving engineering a look at the product early in the design process, mistakes can be corrected and changes can be made while they are still inexpensive. RCP solutions can be used with different real-time solutions in hardware and software such as Waijung, Speedgoat GmbH, dSpace, National Instruments, OPAL-RT and others.

The STM32 F4-series is the first group of STM32 microcontrollers based on the ARM Cortex-M4F core. The F4-series is also the first trybrid in the STM32 series to have DSP and floating point instructions. The F4 is pin-to-pin compatible with the STM32 F2-series and adds higher clock speed, 64 KB CCM static RAM, full duplex I²S, improved real-time clock, and faster ADCs.

Around 60 B.Tech students from EEE, ECE and EIE domains across different campuses of Amrita School of Engineering participated in this workshop on February 16, 2019 at Power Electronic Lab, ASE, Coimbatore. The workshop was conducted as a part of Anokha 2019. The session was offered by Dr. A. Vijayakumari ( Asso. Prof, Dept. of EEE), Mr. S. R. Mohanrajan (Asst. Prof SG, Dept. of EEE) and assisted by I. Sai Chaitanya, Research Scholar, Dept. of EEE.

The session familiarized a direct real-time hardware development tool, “MATLAB Waijung Blockset” for rapid prototyping of power converters with STM32 Discovery Board.

The session started with a brief introduction to RCP and Waijung Software. Then a set of processor in loop and hardware in loop RCP experiments were given as a hands-on session for the participants.

The session was useful and intrigued the young minds to work with STM controller easily and effectively. It motivated them to explore and implement their ideas as hardware prototypes in lab. This session received extremely positive feedbacks from all the participants and some additional sessions with the same controller was conducted for PG students as well.
