Abstract: The
characteristics of traditional series electronic transmission is
studied. The improvement on it leads to a new type of electromagnetism
coupling continuously variable transmission(ECCVT) system. It consists
of a rotor and a stator including iron winding, an additive magnetic
field adjusting winding, a cup-type rotor with special magnetic pole,
inductive slip-rings and power electronic controller. Its specialty is
that the traditional electronic transmission and electromagnetism
coupling are combined and the electricity is transferred unosculantly,
so that the power split is realized. The new system also puts up a
compact topology, good control and stability by the way of frequency
conversion and magnetic field adjusting. The academic analysis indicates
that the system not only has a wide continuously variable range as the
traditional electric motor, but also has a high efficiency. Being used
on an internal-combustion engine vehicle, the clutch and starter are
omitted. It also can be used as the multi-energy power-train assembly of
hybrid electric vehicle accompanied with the electric energy storage
set.
