In order to better implement the transient models of multi-time scale switch in power electronics converter simulation analysis, a simulation method of multiple-timescale models is presented in this paper, and the adaptability of the transient model is illustrated by experimental results. Different applications for multiple-timescale models are also discussed according to the specific switching characteristics reflected by different timescale transient models. In addition, under discrete state event-driven （DSED） simulation system, this paper presents the connection and switching principles between multi-time scale models. As a result, such models can be employed in all-time simulation of power electronics converters.
