Solutions for Hybrid AC-DC Solid State Transformer

Electrical design and protection coordination solution for Solid-State Transformer (SST) systems

I. 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

An 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
