Experimental Comparison Between a MOSFET and GaN FET Inverter for Agricultural Drone UAV’s
Battery-powered UAVs are revolutionizing today’s agriculture where they are used to spray fertilizers and more. These drones use motor drives that need to be lightweight and efficient to maximize working battery life and extend flight time between recharging. Wide-bandgap devices, and specifically Gallium Nitride (GaN) FETs, have demonstrated to improve BLDC motor drives in emobility and robotic applications. This paper will present the characteristics of GaN FETs that reduce weight and improve the motor drive system efficiency.
