STM32 PSU/PFC design workshop


Digital Power Supply and Digital Controller Design with STM32 Hands-On Workshop

Join us for a 4-day hands-on workshop on designing digital power supplies and digital controllers based on the STM32 development ecosystem and Biricha’s power supply design software

Tuesday, November 27 to Friday, November 30, 2018
Future Electronics GmbH, Aschheim, Germany

Learn how to design, code, implement and test stable digital power supply for  both voltage and current mode DC/DC and Digital PFC applications, addressing the most recent industry needs.
All attendees will take part in numerous hands to consolidate the theory though-out each day.
Practical examples will be demonstrated on the STM32 Nucleo-64 development board with our mainstream mixed-signal STM32F334R8 MCU (NUCLEO-F334R8).

Who should attend this workshop?

This hands-on workshop is designed for engineers who are looking to:

  • Learn how to design stable digital controllers for their power applications,
  • Better understand power supply fundamentals, stability and design techniques with a focus on digital power,
  • Get up to speed with digital voltage mode control and peak current mode control using both legacy and modern ICs,
  • Apply modern digital PFC techniques to their solutions.

All participants will receive a complimentary STM32 Nucleo-64 development board (NUCLEO-F334R8) and a free trial license for Biricha's WDS Power Supply Design Software and PLD PFC Loop Design Software.
