230V/250W: Hi-η Sensorless Brushless DC Motor Drive with 30% Reduced Bulk Capacitor Reference Design
The TIDA-00472 is a discrete IGBT-based three-phase inverter for driving brushless DC (BLDC) motors rated up to 250 W: for example: used in cooker hoods: using a sensor-less: trapezoidal control method. The design provides software implementation for DC bus voltage ripple compensation resulting in 30% reduction in the DC bus capacitor requirement and reduced overall BOM cost. The cycle-by-cycle overcurrent protection feature protects the power stage from large current spikes and the board can work up to 65 °C ambient. This design has also been tested to pass EN55014 standards for conducted emissions: Surge and EFT.
