Multi-Stage Power Delivery
01. Grid-to-Bus
High-voltage SiC AFE Rectifiers stabilize the 800V DC bus directly from 13.8kV grid power, ensuring unity power factor at MW scale.
02. Galvanic Isolation
Isolated LLC Resonant converters with planar magnetics bridge the 800V bus to the 48V rack bus with >98% typical efficiency.
03. GaN Point-of-Load
The final conversion stage uses GaN HEMT multi-phase buck converters to deliver ultra-clean 0.7V – 1.1V to the GPU core.
Validated by Science
Before deployment, every architecture undergoes high-fidelity Model-Based Design validation using PLECS and PSIM to ensure stability under 1000A/μs current steps.
Thermal Co-Simulation
Simultaneous modeling of switching losses and liquid cooling manifold pressure drops.
Small-Signal Stability
Predictive control loop analysis for rapid compute-cycle transitions in H100/H200 clusters.
