Development of a Traction Circuit for Battery-powered and AC-fed Dual Source EMU and Running Test Evaluation of the On-board Battery Performance

We have converted an existing AC electric multiple unit train (EMU) into a battery-powered and AC-fed dual source EMU (test train) to allow interoperable service between AC electrified lines and non-electrified lines. This paper describes the features and the test results of the developed traction circuit. Results of the on-board...
