The 96–150 V battery architecture, which is becoming increasingly common in electric mobility systems, is driving new requirements in motor drive design. Applications operating in this voltage range demand fast switching, low conduction losses, and compact solutions with integrated protection and sensing features—capabilities that have traditionally been difficult to combine. EPC addresses this gap with its newly introduced EPC9196 reference design.
EPC9196: High-Performance Inverter Powered by GaN Technology
The EPC9196 is a three-phase BLDC motor driver reference design capable of delivering 25 ARMS output current. This evaluation board is equipped with EPC2304 eGaN® FETs (200 V, 5.0 mΩ max RDS(on)), delivering a combination of high efficiency, fast switching performance, and low EMI. The design specifically targets the following applications:
Steering drive systems in automated guided vehicles (AGVs) and mobile robots
Low- to medium-power actuators and servo mechanisms in industrial robots
Traction motors in light electric vehicles
Technical Specifications and System Architecture
The EPC9196 provides a highly integrated solution, incorporating three half-bridge power stages, gate drivers, current and voltage sensing circuits, and advanced protection features. The system architecture is optimized to deliver high reliability and precise control, which are critical in motor control applications.
Key Technical Features:
Input Voltage Range: 30 V – 170 V
Output Current: 25 ARMS (35 A peak) per phase
Switching Frequency: Up to 150 kHz
dv/dt Control: <10 V/ns (optimized for EMI and acoustic noise reduction)
Current Sensing: Front-end with ACS37003 sensor featuring 400 kHz bandwidth
