A Review on Device-Level Real-Time Simulation of Power Electronic Converters
Résumé
The device-level description of power switches is an emerging topic that
enhances the real-time simulation (RTS) accuracy of power electronic
converters. However, device-level RTS (DLRTS) is challenging due to
contradictions between the additional computing amounts introduced by
nonlinear switch models and the nanosecond-level simulation time step
required by fast switching transients. Therefore, much research has
sought the tradeoff between the accuracy and speed in DLRTSs. In this
article, we review state-of-the-art DLRTS technologies, in particular
for device-level switch models and efficient network solvers. Moreover,
we summarize different applications of DLRTSs and crosswise compare
their performances. We also give some outlooks on future research. This
review not only provides a comprehensive overview of DLRTSs for general
audiences but also provides a technical reference for practitioners. See
