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.

EL SEGUNDO, Calif.—  March 2023 – Efficient Power Conversion (EPC), the world’s leader in enhancement-mode gallium nitride FETs and ICs, has teamed up with SHARGE Technology (SHARGE) to design a 67 W USB PD charger with a power display screen. The Retro 67 fast charger uses EPC’s 100 V GaN FET, EPC2218, which can deliver 231 A pulsed current in a tiny footprint of 3.5 mm x 1.95 mm offering designers a significantly smaller, more efficient device than silicon MOSFET for USB PD fast chargers.

EPC2218 provides SHARGE’s All-GaN fast charger with higher efficiency, state-of-the-art power density and lower system cost.

宜普电源转换公司（EPC）和立锜科技（Richtek）携手推出新型快充参考设计，使用RT6190降压-升压控制器和氮化镓场效应晶体管EPC2204，可实现超过98%的效率。

宜普电源转换公司和立锜科技宣布推出4开关双向降压-升压控制器参考设计，可将12 V~24 V的输入电压转换为5 V~20 V的稳压输出电压，并提供高达5 A的连续电流和6.5 A的最大电流。与高功率密度应用的传统解决方案相比，新型RT6190控制器与EPC的超高效氮化镓场效应晶体管EPC2204相结合，使得解决方案尺寸可缩小20%以上，而且在20 V和12 V输出电压下，可实现超过98%的效率。在不需使用散热器和5 A连续电流下，20 V转5 V的最大升温低于摄氏15度，而12 V转20 V的最高升温则低于摄氏55度。
