Zero-crossing detection with voltage comparator in position detection method based on the AC component of Supposing Neutral Point(SNP) induced sensitivity to noise. In this paper, it is proposed that the ASIC ML4425 should integrate AC component instead of the terminal voltage and phase-locked loop(PLL) was used to determine the proper commutation sequence for the BLDC motor. Basic principle and implementation of the ASIC-based sensorless controller will be presented and experiments will be given to verify the control strategy.
