GDT Series Solid-State Transformer (SST)
Solid-State Transformer (SST) is composed of power-electronic converters, a high-frequency transformer, and semiconductor devices. By means of high-frequency switching, it enables voltage transformation and high-efficiency power transfer. The SST converts medium- and high-voltage AC or DC into 240–800 V DC, eliminating the need for traditional multi-stage conversion. It is suitable for data center power supply, DC distribution, and renewable energy collection/aggregation (e.g., PV and wind), as well as applications such as EV fast charging and energy storage interfacing where compactness, high efficiency, and controllability are required.
Efficiency Enhancement
Adopting SiC MOSFETs and advanced power semiconductor devices, achieving an efficiency of up to 98.5%.
Multi-Terminal DC Integration
Magnetically integrated multi-terminal decoupling enables direct connection of renewable energy sources and energy storage systems, improving renewable-energy utilization efficiency.
High Reliability
High-redundancy modular design combined with DC current-limiting technology ensures high power-supply reliability, allowing elimination of conventional diesel-generator backup systems.
High Integration & Easy Installation
Highly integrated design reduces the overall system footprint by up to 60%.
