Gallium nitride (GaN) helps is making innovative inverter to precisely control motors and robotics
The new era of automation comes with precisely controlled motors and robotics. Today, robots handle various processes for precise and better quality of production and higher productivity. Pick-and-place robots, for instance, are typically found in industries to repetitively perform fine motion control with micrometer precision, and usually far more rapidly than a human. However, for robotics to be successful, precise motor drive control is necessary and that itself depends on advances in electronics.
TI offers an innovative motor control reference design to help engineers create more precise, reliable motor drive and control system designs with the highest power efficiency. One of the noteworthy things about this design is that it utilizes GaN-based transistors that are smaller, faster, and more power efficient than silicon technologies.
3-phase GaN inverter for motor drive and robotics
The three-phase, GaN inverter is intended to drive 200V AC, 2-kW AC servo motor drives and next-generation industrial robotics with fast current-loop control, higher efficiency, more accurate speed, and torque control, the company claims.
The design features six of TI’s LMG3410 600 V 12-A gallium nitride (GaN) power modules. TI says the GaN power module allows 5x faster switching compared to silicon FETs. This optimized switch performance is also said to allow for less power loss, thus allowing the designer to downsize the heat sink. The space savings are beneficial for compact servo drives and motor integrated drives.
