Abstract To solve the problem of excessively high resonant voltage in shift-phase full bridge convertor rectifying voltage output of low-floor light rail vehicle, this paper first analyzes the composition of the voltage, indicating that the voltage is composed of three parts, and analyzes emphatically two parts of the three. Secondly, the paper selectes the most practical topology of RCD snubber, and models rectifying voltage output according to circuit equivalent theory. Moreover, reasonable parameters of RCD snubber are also presented in the paper. At last, the paper presents the simulation result in Matlab, adopting the model and RCD parameters derived above. The topology and parameters are subjected to a prototype equipment to testify its effectiveness.

Key words： Rail transit auxiliary convertor resonant voltage snubber parasitic paremeter
