Solid-State transformer(SST)

SST Core Technical Advantages
As the core equipment of the “Silicon-based Revolution” in power systems, the SST offers significant
general advantages over traditional power supply solutions:
• High Efficiency and Energy Saving: High energy efficiency up to 97.8%.
Eliminates power frequency transformers, resulting in zero no-load loss. Soft-switching
technology combined with intelligent cooling design significantly reduces operational energy
consumption.
• Compact and Flexible: High-frequency design reduces volume by more than 60%.
The modular structure supports flexible capacity expansion, and the field installation cycle is
shortened by 70%.
• Excellent Power Quality: Input current Total Harmonic Distortion (THDi) ≤ 3%, voltage regulation
accuracy ≤ ±1%. No additional APF/SVG configuration is required.
• Multi-source Integration: Suitable for hybrid or multi-scenario access including wind , solar,
storage, and charging piles. Supports integrated operation of “Source-Grid-Load-Storage.”
• Strong Grid Adaptability: Compatible with LVRT/HVRT (Low/High Voltage Ride Through) and
reactive power compensation scenarios. Grid-forming technology provides voltage support and
active inertia.
The SST architecture provides low-voltage DC power distribution interfaces, enabling easy integration
of green energy and energy storage. It simplifies the power supply path to IT loads and effectively
improves access efficiency while reducing overall system costs
