Motor Drive
GaN Reduces Size and Weight, Reduces Audible Noise, Enables Precision Control

There are several applications for brushless DC (BLDC) motors in industrial applications such as robotics, e-mobility, and drones. The small size, thermal efficiency, and high frequency switching capability of GaN FETs and ICs enable more compact motor drives with higher precision and lower audible noise.

Major benefits of a GaN-based motor drives include very short deadtimes for very high motor + inverter system efficiency for longer range, lower distortion for lower acoustic noise, lower current ripple for reduced magnetic loss, lower torque ripple for improved precision, and lower filtering for lower cost. The lower weight and size of the GaN solutions enables incorporation of the drive into the motor housing and supports low inductance, higher power density motors. When configured for 100 kHz frequency, the input filter and the number of capacitors can be dramatically reduced, and the electrolytic capacitors can be eliminated from the board for lower cost, space savings, and higher reliability.
