Hofer powertrain opts for the most future-proof chip technologies and realizes new multilevel power electronics with the latest Gallium Nitride Chip Technology D3GaN (Direct Drive D-Mode) #GaN
German powertrain expert hofer powertrain opts for the most future-proof chip technologies and realizes new multilevel power electronics with the latest gallium nitride chip technology, D3GaN (direct drive D-mode), supplied by VisIC Technologies Ltd., the leader in GaN technology for the automotive industry. Recent tests have shown that the new solution’s power density and efficiency surpass those of silicon-based technology.
GaN semiconductors are the key to efficiency improvements, which increase the driving range and lifespan of electric cars. Hofer powertrain and VisIC Technologies want to build GaN-based power inverters for electric cars, making a technological breakthrough for 800-V battery systems in the automotive sector.
According to hofer powertrain, GaN is the key to a breakthrough in inverter performance, as it is more efficient than silicon- and silicon carbide–based systems.
The system is due to undergo a series of tests under real-world circumstances, and it is expected to surpass expectations, resulting in a more efficient vehicle engine.
This system offers useful insights and in-depth knowledge of short-circuit protection, switching features of the installed GaN transistors, the influence on dV/dt, oscillations during switching, and voltage overshoots, among other things. In addition, the business selects the most crucial electrical and thermal attributes for speedy growth.
A successful client project that serves as a benchmark for comparing the individual advantages of a new 2L inverter with those of an old 2L inverter, both at the subassembly and system levels, yields an in-depth insight.
The subsequent sample stage (A1) has already begun, and it is anticipated that the permanent synchronous motor would operate well under actual test circumstances. The team’s objective is to evaluate and benchmark current systems using test cycles like the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) and demonstrate the system’s exceptional potential for the complete automotive powertrain.
