GaN for Low-cost e-bikes, Drones, and Robotics

GaN for Low-cost e-bikes, Drones, and Robotics

The EPC9193 GaN-based inverter reference design enhances motor system performance, range, precision, torque, all while lowering overall system cost.

EL SEGUNDO, Calif.— March, 2024 — EPC announces the availability of the EPC9193, a 3-phase BLDC motor drive inverter using the EPC2619 eGaN® FET. The EPC9193 operates with a wide input DC voltage ranging from 14 V and 65 V and has two configurations – a standard unit and a high current version:

GaN-Based Low-Voltage Inverter for Electric Scooter Drive System

GaN-Based Low-Voltage Inverter for Electric Scooter Drive System

This paper deals with the application of the latest generation low voltage (up to 80 V) Gallium Nitride (GaN) devices for motor drive applications in the field of electric micro-mobility. A two-level inverter topology oriented to light electric traction (such as electric scooters) with a power rate of 1500 W has been considered. An experimental board using two GaN FETs in parallel connection for each switch of an inverter leg has been arranged. The intrinsic parameters spread of the device, as well as the leakage inductances of both the circuit and the PCB, to evaluate the impact on the current share during both the transient phase and in the steady state have been investigated. In the paper, several simulation runs have been carried out and described. Furthermore, the inverter experimental board has been used to evaluate the phase voltages and currents at different load conditions. Finally, the temperature limits versus phase current variation have been evaluated.

GaN IC縮小馬達控制器和加快eMobility、電動工具、 機器人和無人機的上市時間

GaN IC縮小馬達控制器和加快eMobility、電動工具、 機器人和無人機的上市時間

EPC9176是一款基於氮化鎵元件的逆變器參考設計,增强了馬達控制系統的性能、續航能力、精度和扭矩,同時簡化設計。該逆變器尺寸極小,可集成到電機外殼中,從而實現最低的EMI、最高的功率密度和最輕盈。

宜普電源轉換公司(EPC)宣佈推出EPC9176。這是一款三相BLDC馬達控制逆變器,採用EPC23102 ePower™ 功率級GaN IC,內含閘極驅動器功能和兩個具有5.2 mΩ典型導通電阻的GaN FET。EPC9176在20 V和80 V之間的輸入電源電壓下工作,可提供高達28 Apk(20 ARMS)的電流。這種電壓範圍和功率使該解決方案非常適合用於各種36V~80 V輸入的三相BLDC馬達控制應用,包括電動自行車、電動滑板車、電動工具、無人機、機器人、直流伺服、醫療機器人和工廠自動化。
