Frigate implements rigorous testing including thermal cycling, surge voltage, and insulation resistance tests per AEC-Q200 and IEC standards. Materials and components are sourced to automotive-grade specifications, ensuring long-term durability. Manufacturing processes incorporate statistical process control for consistency across batches. This comprehensive approach guarantees transformers withstand harsh EV operating conditions.
Frigate utilizes planar and toroidal core designs to maximize power density while maintaining electrical isolation. Precision winding techniques reduce inter-winding capacitance and leakage inductance, critical for high-frequency operation. Advanced magnetic materials with high saturation flux density are selected to reduce core volume. These innovations enable compact transformers suitable for space-constrained EV modules.
Frigate employs Litz wire with carefully selected strand diameter and strand count to combat skin and proximity effects. Winding geometries are optimized through 3D electromagnetic simulation to achieve balanced current distribution. The result is significantly lowered AC resistance and thermal hotspots. This optimization improves overall converter efficiency and transformer lifespan.
Frigate uses high-frequency impedance analysis and S-parameter measurements to characterize transformer behavior. Results are cross-validated with finite element magnetic and thermal simulations for accuracy. Transformers undergo accelerated life testing under dynamic switching loads to verify stability. This ensures consistent performance in demanding EV power electronics.
Frigate designs transformers with reinforced insulation layers and uses high Comparative Tracking Index (CTI) materials to prevent electrical breakdown. The creepage and clearance distances exceed automotive standard requirements for 800V and above systems. Epoxy encapsulation and potting compounds enhance mechanical robustness and dielectric strength. These features collectively secure safe operation across critical high-voltage boundaries.
