D3GaN Power Modules for Automotive Inverters Achieving 99.7% WLTP Efficiency
This presentation highlights VisIC Technologies’ latest D3GaN technology, integrated into power modules for inverters driving electric motors in battery electric vehicles. Dyno tests achieved over 130 kW, surpassing SiC performance with the same e-machine. We will present WLTP efficiency results, switching loss data, and insights on implementing lateral GaN in real-world power modules. The talk also addresses key system-level design considerations and limitations when using lateral versus vertical devices.
