Reduced power consumption |
The number of bogies has been increased (3 > 4bogies/car) and
the levitation air gap is reduced (10 > 8mm).
Redundancies have been implemented in the levitation controller and electromagnet system.
The measuring range of the gap sensor has been increased and the control algorithm of the
controller has been improved.
Independent power supply units have been adopted for each bogey. An emergency backup
battery system has been installed.
The capacity of the power supply system has been increased.
