24V, 35W sensorless FOC BLDC reference design with 85 to 265VAC, 0.92PF single-stage PFC

Overview

TopologyPower Factor Correction
Input voltage24 V
IC revision00

Description

For achieving energy efficiency, ceiling and ventilation fans are moving from simple AC induction motors to brushless DC (BLDC) motors. This reference design meets these challenges of higher efficiency and power factor by using a universal main power-supply input from 85 to 265VAC with a single stage power-factor corrected isolated flyback to convert offline voltages and can reach up to 0.92pF in 24VDC. The design also combines a fully integrated and well protected single-chip for sensorless field-oriented control (FOC) brushless motor control.

Features

  • 24V, 35W sensorless FOC drive capable of driving brushless DC (BLDC) motors
  • Highly integrated and protected single-chip, brushless FOC motor controller reduces external part count and audible noise
  • Integrated FOC algorithm with windmilling support, fast start-up, and quiet operation
  • Support closed-loop speed control maintains high accuracy of expected motor speed
  • Reliable start-up and fully protected system with short circuit, overcurrent and blocked rotor protection
  • Single stage PFC to achieve high input power factor (> 0.92), universal input capability (85V to 265V AC) with minimum variation in efficiency
  • Cost-optimized MCUs MSPM0C or MSPM0L offer high-performance analog peripheral integration
  • Optimized small-form factor (SFF) fits for motor integration

Typical applications

  • Air purifier & humidifier, Appliances pumps & fans, Dishwasher, Residential & living fan, Washer & dryer
