To achieve energy efficiency, ceiling fans and ventilation fans are moving from simple alternate-current (AC) induction motors to brushless direct-current (DC) motors (BLDC). An AC-operated BLDC motor requires two sections to run the BLDC motor: the AC-DC power conversion section and the DC to 3-phase AC conversion section. The Texas Instruments 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 a low-voltage DC output. This reference design also combines a fully integrated and well protected single-chip, DRV10983, sensor-less sinusoidal brushless motor controller for low-noise operation.
