Advancements in GaN Motor Drive Inverters Revolutionize UAV Drones for Agricultural Applications

Advancements in GaN Motor Drive Inverters Revolutionize UAV Drones for Agricultural Applications

Modern agricultural techniques have been revolutionized by the integration of unmanned aerial- vehicle (UAV) drones, which are low-voltage battery-operated aircrafts. Smaller drones are utilized for terrain mapping and vegetation monitoring, while heavier, more robust variants are employed for tasks such as spraying and distributing fertilizers and insecticides as well as disseminating seeds and feed with payloads up to 50 kg loads. GaN-based inverters prove to be suitable for UAV agricultural drones since they extend the battery life by improving motor efficiency, courtesy of the higher PWM frequency with sinusoidal excitation. In addition to the efficiency considerations, the higher PWM frequency contributes to a reduction in the dimensions of the DC link, thereby reducing the size and weight of the inverter, which is vital in lightweight aircrafts.
