Intro

  • From 120AC to 24V DC using arduino, and 6A max output.
  • 10A fuse on DC side
  • Arduino topology - Rectify AC, chop it, filter it, that's it.

Terminology

  • Transformerless power supply typically refers to a power supply where a capacitor and resistor are dropping the voltage to a required level. This is valid for 1 amp or less current.
  • Switch mode power supply is one that uses fast, active switching
