For achieving energy efficiency, ceiling fans and ventilation fans are moving from simple AC induction motors to brushless DC motors (BLDC). Operation of BLDC motors from AC supply requires AC-DC conversion with high efficiency and power factor. It also needs an inverter which is controlled efficiently for low noise operation. The reference design TIDA-00652 helps to meet these challenges of higher efficiency and power factor in a simpler way, by using a single stage power supply to convert the AC mains input into low voltage DC output. It also combines a fully integrated and well protected single chip sensor-less sinusoidal brushless motor controller for low noise operation.
