Have you tried digital power control?

awinning

I'm running this RoadTest to give away Exar's XRP7714ILB-FXRP7714ILB-F http://www.element-14.com/community/view-event.jspa?event=2607.for users to test and review

 

I wondered if anyone had used digital power control and how they found it.

  • Hi Alistair,

     

    Like Jorge, I tried and tested a Microchip reference design on digital control. It was a 300W AC/DC converter with PFC, full bridge 12V ZVS converter and multi-phase buck converter. There are 2 DSPic in the design driving 18 FET's (some in parallel), very impressive design. The multi-phase buck (3V3/80A) drove a short circuit (piece of thick copper wire in a water tank). It was stunning to see that the supply was apply to drive the short from startup.

     

    I have samples on my desk of DSPic, in the near future i will have to make this stuff myself :-)
