Abstract :
This paper presents a novel method to supply the power of Maglev when it is running in lower speed. It is realized by adding a high frequency current to the original current of the long stator of linear drive motor. Output voltage model of linear generator is given. Relationship between the linear generator output voltage and the injection harmonic current is derived. Finally, experimental results are given.
