MODULE DETAILS

MODULE 7: Power electronics and power supplies

Nominal duration: 4 weeks (48 hours total time commitment)

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

MODULE PURPOSE

To provide participants with a detailed examination of general power supply concepts ranging from simple unregulated, to a more sophisticated linear or switched-mode power supply and to equip them with the necessary skills to design and troubleshoot power supply systems.
