Influence of output characteristics of Magnetic Levitation Power Supply on magnetic suspension control system

Magnetic levitation power supply(MLPS) is the special power supply onboard for magnetic suspension control system (MSCS), which is influenced significantly by output power and output voltage. The restrictions of the output power to maglev carry ability and dynamic adjustments are discussed, and the influence of output voltage ripple on stable performance of MSCS is analyzed, too. Furthermore, some methods of improving the output characteristics of MLPS are proposed. At the end, the validity of these methods is verified by experiments.
