| Abstract |
The traction drive made out of an induction motor fed by a DPI (Direct PWM Inverter) using GTO's and directly connected to the DC main has significant advantages compared to other solutions. Up to now, the main problem was the limited braking torque available at high speed operation. The best way for achieving this objective is to maintain the magnetizing flux above the nominal speed. This induces a motor voltage that leads to a DC voltage level higher than the DC line voltage. This paper presents methods to improve the braking torque and compares the solutions on a 100 kW prototype. The economical aspects of the problems are discussed as well. |
