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.
