Resonant Inverter, 100 kHz, 100W

DC-DC Power Converters
1

I need to make a Resonant Inverter, with AC output.

  • Application: AC power supply
  • Topology: LLC or other
  • Input: 12V to 24V DC
  • No DC output
  • 100 kHz
  • 100W
  • 0 to 20A continuous
  • constant voltage
  • 0 to 5V
  • Inductive load for galvanic isolation
  • pure sine
  • soft-switched
  • 1/2 bridge or 1/4 bridge

Our load uses AC directly from the secondary of the load-trafo. We will not rectify or filter the secondary of the load-trafo.

What MPS parts are recommended? Seeking FET, gate driver, controller, etc

HR1001B ? HR1200 ?

Interesting problem, just another MPS customer here with some time to kill. LLC converter and get rid of the output rectifiers is probably a good way to go. It regulates by altering the frequency so you need to allow a frequency range on the output. Zero will be achieved at infinite frequency so that looks to be a tricky spec as well. Good luck
