Syllabus

[edit | edit source]

This is a introduction in to power supplies and Switch mode power supply theory. This course will cover,

  • Zenner and lm78xx based linear regulation, and why it doesn't work well.
  • Basic unregulated switching power supplies
  • Voltage feedback regulation
  • Current loop limit regulation
  • Inductor based buck, boost, buck boost, invert, non isolated flyback
  • Capacitor based charge pump, buck, boost, invert

The continuation of this course is EE 330 Switching Power Supplies 2
