What is SST?SST stands for Solid-State Transformer, also known as Power Electronic Transformer (PET). From the perspective of power transmission, a typical SST connects to a 10 kV AC grid on the primary side and outputs approximately 800 V DC on the secondary side. The power conversion process generally involves two stages: AC-to-DC and DC-to-DC (step-down). When the output is used for individual equipment or integrated into servers, an additional stage to step down from 800 V to 48 V is require
