Texas Instruments introduced a three-phase, gallium nitride (GaN)-based inverter reference design that helps engineers build 200 V, 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 reference design can be downloaded at www.ti.com/tool/TIDA-00915.
The reference design features TI’s newest LMG3410 600 V, 12 A GaN power module with an integrated FET, gate driver and protection, announced last year. The GaN module allows the design to switch up to five times faster than silicon FETs, while achieving efficiency levels greater than 98% at 100 kHz and greater than 99% at 24 kHz pulse width modulation (PWM) frequency.
With GaN, designers can optimise switch performance to reduce power loss in the motor, and downsize the heatsink to save board space. Operating the inverter at 100 kHz helps improve torque ripple when used with low-inductance motors. The GaN inverter power stage easily interfaces with microcontrollers (MCU), including TI’s TMS320F28379D drive control system-on-chip, to help dynamically adjust voltage frequency and achieve ultra-fast current loop control.
The company also introduced its new DesignDRIVE Fast Current Loop software with a sub-cycle PWM update techniques that help push current-loop performance in servo drives to less than one microsecond, potentially tripling motor torque response. TI says the software outperforms traditional MCU-based current-loop solutions, and is available free with controlSUITE software.
In addition to the GaN module, the reference design relies on TI’s AMC1306 isolated delta-sigma modulators with current sensing to increase motor control performance. An ISO7831 digital isolator also provides reinforced isolation between the MCU and the design’s six PWMs.
