Abstract
Most electric trains in DC-electrified railways are presently equipped with a
regenerative braking system. On braking, the traction controller of a train can
convert kinetic energy into electrical energy during deceleration of the train only
when other powering trains consume the electrical energy as electrical loads for
the regenerating train in the electrical circuit. Therefore, the traction controller of
the braking train must reduce the electrical power following squeezing control of
regenerative power when the electrical loads are too small in the electrical
circuit, because there are, typically, no other devices to absorb the regenerated
energy in the electrical circuit. However, actual traction controllers have often
reduced regenerative power excessively bec
