The advantage of forward converter design

  • More reliable
  • More efficient



    		•  What's forward converter?
    A power supply switching circuit in which energy is transferred to the transformer secondary when the switching transistor is on. In this circuit minimal energy is stored in the transformer.


    		 What's the difference between forward converter and half bridge converter?

    Forward Converter
    An advanced DC-DC converter topology was good for low voltage and high current applications.
    Key component: Power MOSFET
  • Switching by reliable MOSFET
  • High switching frequency ~ 100K Hz
  • High efficiency & power density
  • Accurate current mode control method
  • Stable in high temperature operation
  • Less parts count & better reliability

    • Half Bridge Converter
    A traditional DC-DC converter topology was good for low power applications (<200W) and cost effective advantage.
    Key component: Switching transistor
  • Switching by bipolar transistor
  • Normal switching frequency ~ 32K Hz
  • Cost effective advantage
  • Traditional voltage mode control
  • Not stable in high temperature
  • Popular for white box PC

    • Most of the 1st tier company like IBM, DELL & HP could not accept half bridge converter since 3~5 years ago, but we still find more than 70% white box PC build-in the out-of-date converter topology.

    All Seasonic PC & IPC power supplies adopt FORWARD CONVERTER design to ensure the best performance.
