后向离散状态事件驱动电力电子仿真方法
A Backword Discrete State Event Driven Simulation Method for Power Electronics Based on Finite State Machine
摘要
Abstract
A backward discrete state event driven (BDSED) simulation method based on the backward quantized state system (BQSS) algorithm is proposed in this paper, to solve the difficult problem of rigid state equations in power electronics systems. BDSED method is implicit, and the key point is to select the correct combination of quantization values, which allows the state variables to approach their quantization values. Each state variable has two possible quantization values at each step, thus enumeration is infeasible in complex systems. What's more, taken into account the constraint and mutual coupling between state variables when determining their quantization values, the question becomes quite difficult. Thus, an implementation approach of BDSED based on finite state machine is proposed in this paper. The simulation algorithm is tested in a converter circuit with non-ideal device models. Simulation results show that BDSED based on finite state machine can efficiently select the combination of quantization values, and its simulation efficiency is obviously higher than DSED as well as traditional time-slicing ODE methods when solving stiff systems such as power converters.关键词
