| Abstract | An innovating system called four-quadrant energy transducer (4QT) has been developed, at the division of Electrical Machines and Power Electronics, Royal Institute of Technology (KTH), Stockholm. It consists of two permanent magnet machines: a double rotor machine (DRM) and a conventional machine (STATOR). The outer rotor of the DRM is connected to the shaft of the STATOR-machine. This system presents a trade-off between series and parallel hybrid architectures. As its name suggests, the transducer can operate in all four quadrants defined from the working point of the Internal Combustion Engine (ICE) in the torque-speed diagram. In a hybrid vehicle, the 4QT allows independent speed and torque of both the ICE and the transmission load. The DRM and STATOR provide respectively the speed and torque differences. 4QT machine prototypes, which integrate the DRM and the STATOR into one unit, have been built. In order to test the performances of the prototypes and measure the system efficiency a laboratory set-up was built. Two more electrical machines are used in the test bench to replace the ICE driving the 4QT and to simulate the transmission load. Each of the four machines is supplied from a common DC link through an inverter. The setup is controlled by a digital signal processor (DSP). Different operation conditions are programmed, resulting in speed and torque set points, which are sent to the bench controller. Mechanical and electrical power meters are installed to measure the efficiency of each machine of the 4QT. Efficiency measurement can be performed at various operating points as well as during the simulation of a drive cycle. This paper presents the equipment and the solutions used to build the test bench. Measuring equipment, and methods will be described. The state of completion of the test bench is illustrated by experimental results from operation tests. Copyright © 2002 EVS19. |
