| Abstract |
Applications of the electric double layer capacitors to railway traction circuits are described by
experimental results with low power traction model circuits. Voltage unbalances among series
connected blocks and cells are practically measured, through hundred cycles of charge and discharge.
The results indicate some examples of reasonable voltage detecting and equalizing methods against
unbalance of individual cell, assuming normal operational modes of typical commuter trains.
Additionally, around 1000V high voltage trial tests by the model circuits with the electric double layer
capacitors are also described, and it shows possibility of application to practical traction circuits in
near future. |
