Study of maximum linear generator output power for Maglev emergency power supply

This paper presents a novel method of emergent power supply for Maglev when it cannot run. It is realized by injecting a high frequency current to the three phase stator windings and adding an extra linear generator winding to magnetic pole. Output power model of linear generator is given. Relationship between the linear generator output power and the injection harmonic current is studied. Finally, experimental results are given.
