AI Calculator "energy pain"
In the AI training cluster, single server power has exceeded 4kW and power systems face triple-threshold challenges:
(a) Efficiency bottlenecks: traditional silicon units are only 95 per cent efficient in the pressure PFC segment, with annual electricity losses exceeding 100, 000 degrees/ thousand units;
(a) Dispersed heat crisis: power module temperature rises > 40 °C, forced to use violence to disperse heat, noise up to 55 dB;
Volume shackles: Magnetic elements over 60% in size, constraining shelf density.
GaN solution to re-engineer AI power source design logic with HF high efficiency, extreme cold.
High pressure segment performance breakthrough: PFC+LLC All Gan
