Load commutated inverters with multiple three-phase configurations are widely used in high-power synchronous motor drives due to its robustness and reliability. However, harmonic problems, poor starting performance and the limited upper frequency are the issues to be addressed. In this paper, a novel six-phase inverter system, consisting of two main three-phase inverters and an additional five-level...
This paper proposes a new stator section crossing method that can overcome the drawbacks of the tow-step and three-step methods used in Shanghai Maglev railway. This method has no descending of propelling force and idleness of PWM converters. The mathematic model and vector control strategy of the permanent magnetic long stator linear machine (PMLSM) are also researched in this paper. The effectiveness...
