Beschreibung
Low-voltage, high-speed drives and low-inductancebrushless motors require higher inverter switchingfrequencies in the range of 40 kHz to 100 kHz tominimize losses and torque ripple in the motor. TheTIDA-00909 reference design achieves this by using athree-phase inverter with three 80 V, 10-A half-bridgeGaN power modules (LMG5200) and uses shuntbasedphase-current sensing. Gallium nitride (GaN)transistors can switch much faster than silicon fieldeffecttransistors (FETs) and integrating the GaN FETand driver in the same package reduces parasiticinductances and optimizes switching performance toreduce losses, thus allowing the designer to downsizeor eliminate the heatsink. The TIDA-00909 offers a TIBoosterPack™ Plug-in Module with a compatibleinterface to connect to a C2000™ MCU LaunchPad™Development Kit for easy performance evaluation.
