Abstract

Abstract:

There is a lack of researches on parameter selection and simulation accuracy of the high-order event-driven simulation method for power electronic converters. Considering their characteristics， the simulation process of power electronic converters is analyzed based on event-driven architecture， and an event-driven simulation method for power electronic converters is proposed. Researches and simulations are conducted on the converters' parallel operation and transient process with parasitic parameters which are two typical ill-posed problems of converters. Non-linear relationships between algorithm orders， quantum sizes and simulation accuracy are concluded， and methods for parameter selection and simulation accuracy optimization under different circumstance are summarized. The feasibility and scalability of the proposed event-driven simulation method is proved by the simulation result.

Key words: power electronic converter, event driven, numerical simulation, quantized state system
