1964. Inauguration in Japan of the Tokaido
Shinkansen, the world's first high-speed line
(210 km/h) with a 25,000 V and 60 Hz AC
system, in Booster configuration.

Europe. The system used is 25,000 V and 50
first period of the application of power Hz in AC, in HV configuration (2x25 kV).
electronics in traction can be placed, still
conserving the direct current motor. This
traction revolution began with the
application of the silicon diode, and then,
during the 1970s, with that of the thyristor.
Silicon diodes make it possible to definitively
strengthen the development of electric
traction at 25,000 V and 50 Hz in AC, diesel
traction with three-phase/continuous
electric transmission, and the replacement of
mercury rectifiers in traction substations
(this technology had been established since
1927 regarding the use of rotating machines
for the direct generation of direct current). SNCF

The first experimental application of the
silicon diode is recorded in the last BB-12000
locomotives of the SNCF, in 1960.

1970. In the case of direct current, fast
thyristors allow the chopper to be developed
in Japan.

1979. The five prototype electric locomotives
of the E 120 series of the state company DB
appear in Germany, with asynchronous
motors, and which were the pioneers of
three-phase traction in Europe. In 1987, the SNCF

reception of 60 E 120 locomotives begins in
Germany. Previously, in Japan, three-phase 1985. The beginning of the second period of
traction had already been applied in various the application of power electronics in
train units. traction can be placed in the mid-1980s,
replacing the direct current traction motor
with the three-phase, asynchronous or
synchronous motor. The development of the
GTO thyristor and the microprocessor
allowed the definitive introduction of three-
phase traction until the year 2000. As of this
year, IGBT transistors displace GTOs.
