BLDC Ceiling Fan Controller with Sensorless Sinusoidal Current Control


Design files


This reference design is a brushless DC ceiling fan controller that runs from AC power.  It features the DRV10983 24-V 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 25 kHz for minimized torque ripple and audible noise
  • Universal AC operating voltage range 90 Vac to 265 Vac
  • Tightly regulated 24V dc achieves ±1% speed regulation throughout input voltage range
  • AC switching produces only 0.6 % ripple on 24 Vdc for optimal acoustic performance
  • AC/DC efficiency is >85% at all load and line conditions to meet stringent energy efficiency requirements
