High‑Efficiency GaN Motor Drive Control Solution for BLDC and Servo Motors

View Detailed Reference Design

Features and Benefits

Compact GaN servo drive with integrated gate drive and sensing
Accurate current sensing improves torque regulation and dynamic response
Adjustable 25–100 kHz PWM with fine dead time control for low-noise efficiency
GaN efficiency removes need for external cooling
Small PCB footprint with optional LC/LCL filtering for clean output and motor integration
Compatible with multiple controllers, supporting 50–750 W across diverse motor types

Electrical Requirements:

Input Voltage: 48–58 V battery source
Output Voltage: 50–750 W
Board V1 Output: Conventional GaN switching waveform
Board V2 Output: Sine wave output generated through LC/LCL filtering

Control & Feedback Requirements:

PWM Frequency: 25–100 kHz
PWM Tuning Parameters: Switching frequency and dead time adjustment
Current Sensing Method: In-line sensing, two-phase measurement (U and W)
Scalability: Configurable sense resistor and amplifier gain

Mechanical Requirements:

PCB Size: 40 × 50 mm
Setup Variations: Extended cable connection between driver board and motor. Driver board mechanically integrated within the motor assembly
Thermal Constraints: Passive cooling only (no heatsink and no forced airflow)
Motor Load: MINAS A6 48 V, 400 W (MSMD04BL1S). Hollow shaft BLDC motors

Protection Requirements:

Provision for DC bus back EMF energy dissipation
