2.3 Non-contact power supply
The principle of non-contact power supply is an electro-magnetic coupling, and it can be
understood as an special style of a transformer, by which electric power is supplied to the OHV.
There is a power cable on the track and alternate current is constantly supplied from the power
supply panel on the ground (Normally it is 400V A.C and 5kW output). Shinko uses 8.66 kHz of
the alternate current for the main power supply. About 300kHz and 350kHz signals are
superposed on the 8.66 kHz main component for realizing the communication between OHV and
ground controller.
