TIDA-00913 48V 3-Phase Inverter with Shunt-based In-line Motor Phase Current Sensing Reference Design | TI.com

TIDA-00913: The TIDA-00913 reference design realizes a 48V/10A 3-phase GaN inverter with precision in-line shunt-based phase current sensing for accurate control of precision drives such as servo drives. One of the largest challenges with in-line shunt-based phase current sensing is the high common-mode voltage transients during PWM switching. The INA240 bi-directional current-sense amplifier overcomes this problem using enhanced PWM rejection. The reference design provides an output voltage from 0 to 3.3V, scaled to ±16.5A with 1.65V mid voltage for high phase-current accuracy over the entire temperature range. The TIDA-00913 offers a TI BoosterPack compatible interface to connect to a C2000 MCU LaunchPad™ development kit for easy performance evaluation.

Isolated IGBT Gate Driver Evaluation Platform for 3-Phase Inverter System Reference Design

TIDA-00195: The TIDA-00195 reference design consists of a 22kW power stage with TI’s new reinforced isolated IGBT gate driver ISO5852S intended for motor control in various applications. This design allows performance evaluation of the ISO5852S in 3-phase inverter incorporating 1200V rated IGBT modules of current ratings ranging from 50A-200A. Some of the important functionality and performance evaluated are short circuit protection using DESAT detection, Soft-shutdown, effectiveness of the Active Miller Clamp at different inverter dv/dt, and ESD/EFT performance of IGBT gate driver at system level derived from adjustable speed electrical power drive systems (IEC61800-3). Piccolo launch pad LAUNCHXL-F28027 is used to generate the PWM signals required for controlling the inverter.

TIDA-00909 48V/10A High Frequency PWM 3-Phase GaN Inverter Reference Design for High-Speed Drives | TI.com

TIDA-00909: Low voltage, high-speed drives and/or low inductance brushless motors require higher inverter switching frequencies in the range of 40 kHz to 100 kHz to minimize losses and torque ripple in the motor. The TIDA-00909 reference design achieves that by using a 3-phase inverter with three 80V/10A half-bridge GaN power modules LMG5200 and uses shunt based phase current sensing. Gallium nitride (GaN) transistors can switch much faster than silicon FETs and integrating the GaN FET and driver in the same package reduces parasitic inductances and optimizes switching performance reducing losses, thus allowing to down-size or eliminate the heatsink. The TIDA-00909 offers a TI BoosterPack compatible interface to connect to a C2000 MCU LaunchPad™ development kit for easy performance evaluation.
