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.

宜普電源轉換公司（EPC）和立錡科技（Richtek）携手推出新型快充參考設計，使用RT6190降壓-升壓控制器和氮化鎵場效應電晶體EPC2204，可實現超過98%的效率。

宜普電源轉換公司和立錡科技宣佈推出4開關雙向降壓-升壓控制器參考設計，可將12 V~24 V的輸入電壓轉換爲5 V~20 V的穩壓輸出電壓，並提供高達5 A的連續電流和6.5 A的最大電流。與高功率密度應用的傳統解決方案相比，新型RT6190控制器與EPC的超高效氮化鎵場效應電晶體EPC2204相結合，使得解決方案尺寸可縮小20%以上，而且在20 V和12 V輸出電壓下，可實現超過98%的效率。在不需使用散熱器和5 A連續電流下，20 V轉5 V的最大升溫低於攝氏15度，而12 V轉20 V的最高升溫則低於·攝氏55度。

Richtek, the global leading analog IC design company has teamed up with EPC, the leading provider of gallium nitride (GaN)-based power management technology to launch a new reference design for fast charging applications, achieving high power density and up to 98% efficiency.
