Beschreibung
Low-voltage, high-speed drives and 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 this by using a three-phase inverter with three 80 V, 10-A half-bridge GaN power modules (LMG5200) and uses shuntbased phase-current sensing. Gallium nitride (GaN) transistors can switch much faster than silicon fieldeffect transistors (FETs) and integrating the GaN FET and driver in the same package reduces parasitic inductances and optimizes switching performance to reduce losses, thus allowing the designer to downsize or eliminate the heatsink. The TIDA-00909 offers a TI BoosterPack™ Plug-in Module with a compatible interface to connect to a C2000™ MCU LaunchPad™ Development Kit for easy performance evaluation
