为优化中低速磁浮列车悬浮控制器,采用LLC谐振变换器拓扑加buck二次稳压结构,研制了270~380 V输入、多路低压输出的悬浮控制电源。该控制电源因高功率密度有利于悬浮控制器的小型化和轻量化。试验结果证明了该种悬浮控制电源的优越性。
In order to optimize the suspension controller of mid-low speed maglev train, LLC resonant converter topology plus buck secondary regulator structure was used to develop 270-380 V input and multi-channel low-voltage output suspension control power supply. The control power supply is conducive to the miniaturization and weight reduction of the suspension controller due to its high power density. The test results demonstrate the superiority of this kind of suspension control power supply.
