Gasgoo Awards 2023 applicant:High efficiency GaN 3-in-1 motor inverter from Shanghai EVBG Drive Co., Ltd.

Product: High efficiency GaN 3-in-1 motor inverter 

Description

1. Working voltage range: 240-420VDC  2. Peak power: 35kW  3. Peak current: 165Arms  4, peak efficiency: 99.34%  5, high power density, excellent NVH performance

Unique advantages

1, high power density: the power unit adopts four GaN devices in parallel design, compact structure and small volume;  2, high efficiency: the maximum efficiency of the controller reaches 99.34%, and the efficiency MAP greater than 90% accounts for 93.58%;  3, low cost: efficiency and SiC is equivalent, but the cost is relatively lower;  4, scalability: power device parallel design is easier to expand to different power level platforms, adapt to different needs;

Application

BEV/PHEV and other electric vehicle power system

Prospect

GaN devices have unique advantages such as higher efficiency (compared with IGBT) and lower cost (compared with SiC), and with the development of GaN technology, it is believed that the application of electric systems in the future will be more and more extensive.
