Learn how to design MCU-controlled digital power supplies and PFCs.

Learn how to design MCU-controlled digital power supplies and PFCs.

Join this workshop to learn how to design stable analog and digital control loops in both voltage mode and current mode for DC/DC and Off-Line Applications.

During 4 days of intensive engineering training and lab-based exercises, you will design, code, implement, and test several digital power supplies in our well-equipped laboratory.

The design practices taught in the class can be applied to any MCU. In this course, all lab exercises implement ST’s Arm®-based STM32G474. 

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 implemented using the STM32 MCU
  • Apply modern digital PFC techniques to their solution

All attendees will receive:

  • 4 days of intensive engineering training and lab-based exercises
  • All necessary software templates and easy to program exercises to start you on your digital power projects
  • Workshop material, lab notes, lunch and refreshments
  • Hands-on practice for this unique time only using new, top-of-the-line Rhode & Schwarz MXO-5 oscilloscopes provided by ST
  • A free 12-month license for Biricha's Power Supply Design Software ST-WDS and PFC Loop Design Software ST-PLD
