The Data Center Solid State Transformer (SST), also known as the Power Electronic Transformer (PET), represents the next generation of green power distribution for mission-critical facilities. Built on the core philosophy of Power Electronic Building Blocks (PEBB), it utilizes an advanced modular series-parallel topology.
Unlike traditional transformers, the SST enables millisecond-level voltage regulation and fault isolation. It serves as an "Energy Router," providing flexible access for various voltage levels and power forms (AC/DC), making it the ideal energy heart for high-density server environments.
Product Features
- Modular PEBB Architecture: The "building block" design supports hot-swappable power modules and redundant configurations (N+1 or N+X), significantly simplifying maintenance and enhancing system reliability.
- Extreme Space Efficiency: Compared to traditional oil-filled or dry-type transformers, the SST reduces physical footprint by 30% to 50% and weight by up to 60%, reclaiming valuable floor space for server racks.
- Hybrid AC and DC Access: It naturally supports both High-Voltage DC (HVDC) input and Low-Voltage DC (LVDC) output, perfectly aligning with the modern trend of DC-powered data centers and reducing multi-stage conversion losses.
- Active Power Quality Control: Features integrated harmonic suppression, reactive power compensation, and voltage sag support, ensuring consistent power delivery even during grid instability.
- Integrated Intelligent Monitoring: Built-in high-precision sensors and communication networks allow for real-time tracking of voltage, current, and temperature, supporting predictive maintenance via BMS or DCIM systems.
Environmental Requirements
- Operating Temperature: -5°C to +45°C (Customizable range from -20°C to +55°C); Storage Temperature: -40°C to +70°C.
- Relative Humidity: 5% to 95% (Non-condensing).
- Operating Altitude: Standard ≤ 2000m (De-rating designs available for high-altitude regions).
- Cooling System: Forced air cooling or liquid cooling options, compatible with precision air conditioning and cold plate systems in data centers.
- Protection Rating: Standard indoor IP20 or IP30 enclosures (Higher protection grades available upon request).
Applicable Scenarios
- Hyperscale Data Centers: Meeting the massive power demands of AI and cloud computing while optimizing Power Usage Effectiveness (PUE).
- Edge Computing Nodes: Leveraging the compact size of SST to provide high-capacity power in limited physical spaces.
- Sustainable "Solar-Storage-Charging" Centers: Facilitating the direct integration of PV and energy storage systems via a DC bus for localized green energy consumption.
- Smart Industrial Factories: Providing high-quality, interference-free flexible power for precision manufacturing and automated production lines.
