Environment friendly Energy Conversion (EPC), a US-based firm recognized for its enhancement-mode gallium nitride (eGaN) energy units, has introduced the launch of a high-performance 25 ARMS, 3-phase BLDC motor drive inverter reference design.
The EPC9196 inverter, powered by the EPC2304 eGaN FET, is tailor-made for medium-voltage purposes (96-150 V) in battery-powered motor drives. This consists of makes use of in steering programs for automated guided automobiles (AGVs), traction motors in compact autonomous automobiles, and exact motor joints in robotics.
EPC emphasizes that this new launch gives system designers with a compact and environment friendly answer that accelerates improvement and optimizes efficiency within the 25-400 ARMS software vary. The corporate has additionally just lately unveiled its EPC2367, a 100 V eGaN FET.
The EPC2304 is rated at 200 V and incorporates a typical on-resistance (RDS(on)) of three.5 mΩ in a thermally enhanced QFN bundle, chosen for its low resistance and excessive efficiency in compact designs. This helps the EPC9196 obtain part currents of as much as 35 Apk (25 ARMS) at switching frequencies reaching 100 kHz, leading to low switching losses, minimal useless time, and a clean motor drive profile, even at excessive PWM speeds.
Key options of the EPC9196 embody a large enter voltage vary of 30-170 V, built-in gate drivers, housekeeping energy, present and voltage sensing, over-current safety, thermal monitoring, and dv/dt management optimized for motor drive purposes (lower than 10 V/ns). The inverter is appropriate with numerous motor drive controller platforms from Microchip, ST, TI, and Renesas, and is appropriate for each sensorless and encoder-based management configurations.
Marco Palma, Director of Motor Drive Programs and Functions at EPC, acknowledged, “With the introduction of the EPC9196, we’re enabling engineers working in robotics, AGVs, and compact EVs to take full benefit of GaN’s superior efficiency with out redesigning for prime present.”
This innovation positions EPC as a key participant in advancing motor drive expertise for numerous purposes.
