Flyback

Used for: Voltage conversion and isolation at low power

Pros:

  • Simplest isolated conversion topology
  • No output choke as in forward converter
  • Can be very simple to stabilise

Cons:

  • Only suits lowish power to around 100W
  • Hi output riupple current, >DC current
  • Needs a transformer gap
  • Transformer approximately scales in size with power. Forward doesnt
