| Abstract |
A full electric gearbox consisting of two motor/generators controlled by inverters for continuous
transmission of mechanical energy with a high spread of speed has been investigated. The electronic power
conversion is comprised of two dc-link connected voltage source inverters (VSI) Further the use of directcoupled
matrix converter (MC) has been put up for discussion on this occasion. The electromagnetic
converter is based on two permanent magnet excited synchronous machines with special arrangements of
the magnetic circuit for higher torque utilisation in the overload region. To achieve a higher efficiency the
basic construction has been improved and a special canned motor construction based on air-gap windings has
been investigated. A new control principle for fast dynamic behaviour adapted on the specifications of
transmission has been developed. The basic functions of the conversion system are verified in a typical
environment of hybrid vehicles where the electronic gear-box is a part of an automatic transmission with
electrical power splitting. |
