Description
Product Description
Solid-state transformers (SSTs), also known as power electronic transformers, are based on the core concept of Power Electronic Building Blocks (PEBB). They generally employ a modular series-parallel topology to facilitate the flexible integration of varying voltage levels, capacity ratings, and forms of electrical energy, thereby enabling adaptable configurations for diverse application scenarios.

Green AI Data Centre Power SolutionMulti-Scenario Solutions Based on Solid-State Transformers (SST)1. Industry Background and Pain Points1.1 Industry BackgroundIn the AI large-model era, the power density of a single data-centre rack has jumped from the traditional 8 kW to 50–100 kW+, and total electrical load is moving from tens of megawatts to hundreds of megawatts. Power systems that are highly efficient, space-saving and quick to deploy have become the core competitive advantage of computing infrastructure.1.2 Four Pain -
Medium-Voltage Direct-Connect Ultra-Fast Charging StationAn SST-Based Solution for Next-Generation EV Charging1. Industry Background and Pain Points1.1 Industry BackgroundWith more than 30 million EVs on the road, users now expect charging to feel like refuelling. That demand has driven the shift to ultra-fast charging (350 kW+, 800 V platform). But the conventional "transformer + charger" station architecture hits a systematic wall in power density, efficiency and utilisation of the grid connection.1.2 Four Pain Points of Traditional Charging Station -

Electrical design and protection coordination solution for Solid-State Transformer (SST) systemsI. Technical Bottlenecks in SST System IntegrationMulti-Cabinet Coordination Timing Mismatch The power electronic protection response of the power cabinet (SST) operates at the microsecond level, while the relay protection of the high-voltage cabinet operates at the millisecond level. This timing discrepancy creates a "blind zone" in protection coordination during faults, exposing power semiconductor devices to risks of overvoltage and overcurrent damage. The inherent breaking time of the high-v
