Infineon Technologies EVAL_MTR_48V150A_GaN Evaluation Board
Infineon Technologies EVAL_MTR_48V150A_GaN Evaluation Board is a high‑performance, low‑voltage motor‑drive platform designed to showcase the capabilities of CoolGaN™ 80V G3 transistors in high‑current applications. Developed for system application engineers, the board supports motor‑drive development up to 48V and 150A, making it well‑suited for next‑generation brushless direct current (BLDC) and permanent magnet synchronous (PMSM) motor systems. The Infineon EVAL_MTR_48V150A_GaN integrates eight parallel CoolGaN transistors in a half‑bridge configuration, enabling high‑efficiency operation (up to 99%) at switching frequencies from 50kHz to 100kHz.
Complementing the power stage are Infineon’s 1EDN7116U TDI EiceDRIVER™ gate drivers, which are optimized for fast and precise GaN switching, and three XENSIV™ TLE4972 magnetic current sensors that deliver accurate phase‑current measurement across all supported switching frequencies. The board accepts a battery input range of 14V to 66V and produces an AC output from 0V to 19.5V at current levels between 110A and 160A, enabling realistic evaluation under demanding load conditions. Overall, the EVAL_MTR_48V150A_GaN serves as a comprehensive reference design for engineers seeking compact, high‑efficiency, GaN‑based motor‑drive solutions.
