Pseudo-original: The development of 400A/650V three-level customized modules for photovoltaics is progressing smoothly, and mass delivery has begun. The production capacity is currently stable, and the terminal performance is good. The development of 800A/750V dual-sided heat sink modules for vehicle use is progressing smoothly, and small-scale delivery has started after passing relevant vehicle reliability tests and system tests. The smooth development of the vehicle-use 750V 12-inch chip and its corresponding module has enabled rapid scaling. The development and verification of 12-inch 1700V high-performance freewheeling diodes and 1700V IGBT chips have been completed.
