EPC adds new reference design for motor drives
Efficient Power Conversion Corporation (EPC) has introduced the GaN-based EPC91200, a fully configured motor drive inverter reference design for a variety of industrial and battery-powered applications.
The EPC91200 is designed for 3-phase brushless DC (BLDC) motor drive applications and features the EPC2305, a 150 V 3.0 mΩ RDS(on) GaN FET. The EPC91200 supports wide voltage ranges from 30 V to 130 V, making it suitable for 80 V and 110 V battery systems commonly used in industrial automation, agricultural machinery, and material handling equipment like forklifts.
The board supports up to 60 Apk (40 ARMS) maximum output current with a switching frequency of up to 150 kHz. Its optimised PCB layout and advanced GaN technology are designed to reduce resistance and heat generation for improved performance. Integrated features include current sensing, voltage monitoring, overcurrent protection, and temperature sensing for robust operation.
It works with multiple controller boards from well known manufacturers like STMicroelectronics, Texas Instruments, and Microchip.
Its compact design (130 x 100 mm) includes a pre-configured shaft encoder/Hall sensor interface and supports Field-Oriented Control (FOC) techniques. Engineers can easily measure critical signals and optimise system performance using built-in test points.
“With the EPC91200, we provide engineers a versatile, off-the-shelf motor drive solution, showcasing the efficiency, reliability, and adaptability of GaN technology in modern power systems,” said Alex Lidow, CEO of EPC.
The EPC91200 reference design boards are priced at $780.00. The EPC2305 is priced at $3.56/ea in 3Ku reels.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
