| Abstract: | Combined with the principle of EMS(electric magnetic suspension) and PEMS(permanent electric magnetic suspension),each circuit of the chopper is researched,by theory analysis,the rule of chopper in single control cycle as well as long time is studied,and the impact on the current changing speed in long time is showed,then the expression of stable current to PWM occupancy proportion is educed.How to choose a reasonable control cycle to ensure the chopper work well is studied,lastly,the chopper of PEMS could ... |
