ABSTRACT = {The disadvantages in power system with traditional industrial frequency 
transformer can be resolved by Solid State Transformer (SST). Cascaded SST 
can be transformerless connected to the high voltage grid. However, the output 
performance and reliability of cascaded SST are seriously influenced by DC 
voltage balancing problem which exists in cascaded configuration. In this paper, 
a DC voltage balancing strategy based on active vector correction is proposed. 
This strategy is characterized by on-demand active power and equal reactive 
power among modulars. Then, a quantitative analysis method is presented to 
validate active power adjusting ability of the traditional and the proposed 
strategies. Simulation and experimental results verify the feasibility and validity 
of these analysis and strategy.},
