High Voltage BLDC Driver
The High Voltage BLDC Ceiling Driver offers a versatile, efficient solution for high-performance motor control. It supports input voltages from 90 to 300VAC and features programmable high voltage output with power factor correction (PF >0.95 at even 20% load) and efficiency exceeding 95% across various load ranges. The motor operates sensorless, with voltage up to 450VDC and a power capacity of up to 400W. The integrated motor drive includes a self-biased half-bridge for up to 400W, supports multiple control algorithms (trapezoidal, sinusoidal, FOC), and provides comprehensive system protection and monitoring
