This reference design is a complete solution for a brushless DC ceiling fan controller that runs from AC power.  It features the DRV10983 24V three-phase motor driver to drive motors with sinusoidal current and sensorless control.  The UCC28630 converts 90-265 VAC into 24 VDC.  The MSP430G2201 value-line processor decodes infrared signals for speed control.  The included firmware allows easy integration with standard infrared remotes based on the NEC transmission protocol.

  • Sinusoidal sensor-less control at 25kHz for minimized torque ripple and audible noise
  • Universal AC operating voltage range 90Vac-265Vac.
  • Tightly regulated 24Vdc achieves ±1% speed regulation throughout input voltage range
  • AC switching produces only 0.6% ripple on the 24Vdc, for optimal acoustic performance
  • AC/DC efficiency is >85% at all load and line conditions to meet stringent energy efficiency requirements
