EPC91120 Compact Three-Phase Inverter

EPC inverters feature high power density for 48 V robotics, drones, and mobility platforms

Image of EPC EPC91120 Compact Three-Phase InverterThe EPC EPC91120 is a high-power-density, low-profile, three-phase BLDC inverter that is optimized for robotics, e-mobility, and industrial motion control.

Powered by three EPC23102 100 V monolithic GaN ePower® stage ICs configured in a three-phase bridge with integrated gate drive and protection, the EPC91120 delivers high efficiency, fast switching, and a compact footprint that is ideal for space- and weight-constrained systems.

Features
  • Compact, lightweight inverter
    • Ultra-small two-layer PCB with optimized thermals for in-joint or in-body mounting
    • High power density for 48 V robotics, drones, and mobility platforms
  • High-performance GaN power stage
    • Three EPC23102 100 V ePower stage ICs provide a low-loss three-phase bridge
    • Fast switching enables reduced magnetics size and a lower total system mass
    • Low parasitics and an integrated driver improve dynamic performance
  • Robust electrical envelope
    • Input voltage: up to 60 V (nominal 48 V systems)
    • Phase current: up to 30 ARMS continuous depending on cooling
    • Ideal for joint actuators, wheel motors, and compact high-torque drives
Applications
  • Humanoid and collaborative robot joints
  • Robotic arms, manipulators, and precision actuators
  • e-Mobility: e-scooters and micromobility traction inverters
  • UAV propulsion and gimbals
  • Compact industrial automation drives
